industry development

power automation equipment refers to the equipment that controls, monitors, protects, operates and manages the power system (including electricity and power plants), including both hardware and software. It can be mainly divided into relay protection devices, substation automation, dispatching automation, distribution automation, energy metering and billing automation, power market, etc. The development of power automation industry is closely related to power investment. The market capacity of power automation products is about 6% - 10% of power investment. Since 2003, China's power supply has been tight and the power industry has expanded. However, due to the serious phenomenon of "heavy power generation and light transmission, regardless of supply", the promotion effect on the power automation industry is limited. With the saturation of power investment, the investment demand for electricity has been put on the agenda, and the market demand for power automation equipment has also increased significantly

according to the "Eleventh Five Year Plan" of the State Grid Corporation of China and the southern power company, the total investment of the State Grid Corporation of China during the "Eleventh Five Year Plan" period is nearly 900billion yuan, and the total investment of the southern power company is about 300billion yuan. In this way, the total investment of China's electricity will reach 1.2 trillion yuan, which is 2.4 times that of the "Tenth Five Year Plan" period. This has led to a sharp increase in the demand for power transmission and transformation equipment, of which the power automation industry has a market demand of at least 24 billion yuan per year. Take 2007 as an example, in 2007, the investment in national power infrastructure was 549.3 billion yuan, of which the investment in power generation infrastructure was 304.2 billion yuan, a year-on-year decrease of 4.81%, and the investment in power infrastructure was 245.1 billion yuan, a year-on-year increase of 17.1%. Affected by it, the power automation industry has also maintained a rapid growth momentum. Statistics show that 45 major enterprises, accounting for about 60% of the total main business income of the industry, achieved a total main business income of 16.8 billion yuan in 2007, an increase of 12% year-on-year. [? The main business income of major relay protection and automation equipment enterprises in China in 2006 and 2007 is shown in Table 1 and table 2 respectively. Table 3 lists the total labor productivity of some relay protection and automation equipment manufacturers in 2007. In the table, Nanrui Jibao, Sifang Jibao, a relay, Panang technology and DeWitt are Nanjing Nanrui Jibao Electric Co., Ltd., Beijing Sifang Jibao Automation Co., Ltd. and a Cheng relay respectively The abbreviations of Co., Ltd., Nanjing paneng Power Technology Co., Ltd. (yuanlidao Technology Co., Ltd.) and Beijing DeWitt Power System Automation Co., Ltd. these companies will use the abbreviation?] below

in the 2007 "Eleventh Five Year Plan" power planning adjustment report, the State Power Corporation increased the original "Eleventh Five Year Plan" power investment of 858.6 billion yuan to 1130 billion yuan. In this way, the investment amount of power construction and transformation in the three years after the "Eleventh Five Year Plan" will increase from the original planned 650billion yuan to 920 billion yuan, with an average annual investment of about 310 billion yuan. In 2008, China's power actually completed an investment of 288.5 billion yuan, the first time in many years to exceed the investment in power supply (287.9 billion yuan). Affected by this, the power automation industry has also achieved great development, and the main business income of most enterprises has increased to varying degrees (see Table 4 for the main business income of some relay protection and automation equipment manufacturing enterprises in 2008)

the increasing investment in electricity in the late period of the Eleventh Five Year Plan provides a rare development opportunity for power automation equipment manufacturers. In order to cope with the adverse effects of the world financial crisis, on November 5, 2008, the State Council issued 10 measures to expand domestic demand, including improving rural power construction and accelerating urban power transformation, and including power construction in "accelerating the post disaster reconstruction of earthquake stricken areas". In order to implement the measures of the State Council on expanding domestic demand, on November 12, Nanfang power company said that it would invest about 30billion yuan a year for urban reconstruction and agricultural improvement on the basis of the original plan of 110billion yuan from 2009 to 2010. On November 14, State Grid Corporation of China said that in the next two to three years, the scale of power investment will reach 1.160 billion yuan, with a new investment of 610 billion yuan. According to the plan of the State Grid Corporation of China to increase investment by 100billion yuan and 110billion yuan in 2009 and 2010 respectively, the total investment of the two companies will reach 1.4 trillion yuan in the next three years, and the investment in electricity in the next two years will increase by more than 40% on the basis of the original plan. This will bring huge business opportunities for power automation manufacturing enterprises, and key enterprises will fully benefit. In particular, the construction and transformation of urban and rural areas will increase the demand for secondary equipment with voltage levels of 110 kV and below. Medium and low voltage power automation equipment manufacturers will usher in a vigorous development opportunity

market competition pattern

the market competition pattern of power automation industry can be divided into two different fields: high-end market (220 kV and above voltage level) and medium and low-end market (110 kV and below voltage level). Foreign manufacturers mainly enjoy a certain share in the high-end market. However, in recent years, domestic equipment has occupied a dominant market position because it is more suitable for the domestic operating environment. At present, in the high-end market of power system and power generation system (each overall situation, Provincial Bureau and large capacity unit power generation system), a relatively monopoly situation has been formed by a few large manufacturers, such as Nari Jibao, Guodian Nanzi, Guodian Nari, XJ electric, Sifang Jibao, etc. Due to the relatively low technical difficulty of products with voltage levels of 110 kV and below, a large number of manufacturers including Dongfang Electronics, Panang technology, Jicheng Electronics Co., Ltd. (hereinafter referred to as "Jicheng Electronics"), Wanlida, Jinzhi technology, DeWitt, etc. are participating in the middle and low-end market, and the competition is very fierce

in terms of markets in different product areas, in addition to the strong comprehensive strength of NARI Group, which plays the role of market leader in the segment (its subordinate Nari Jibao and Guodian Nari occupy the leading position in the field of relay protection and power automation respectively), in general, the segment markets basically have their own strengths. For example, Guodian Nari has considerable strength in the field of distribution automation and has made rapid progress in the relay protection market; XJ Electric has considerable advantages in the field of distribution automation; Dongfang Electronics has a strong market influence in the field of dispatching automation and substation automation; Jinzhi technology occupies a large share in the power plant auxiliary power automation market; As a leading enterprise of medium and low voltage secondary equipment in China, paneng technology has strong competitive advantages in the field of medium and low voltage integrated automation and county-level dispatching automation. At present, large manufacturers in the middle and low-end market of power automation mostly adopt the focus strategy, focusing on their own market segments, so as to concentrate resources to establish the core competitiveness of enterprises and gradually cultivate the operation ability of large-scale products

on the other hand, the power automation industry can be divided into the market within the power system and the market outside the power system. NARI Group, Guodian Nanzi, Sifang Jibao, XJ electric, Dongfang Electronics and other traditional power automation equipment suppliers are mainly concentrated in the power system market

in the power system, the protection of lines and transformers above 110 kV and the protection, dispatching and provincial dispatching of units above 100 MW are mainly shared by Nari Jibao, Guodian Nanzi, Guodian Nari, Sifang Jibao, XJ electric, Beijing Kedong Power Control System Co., Ltd. of China Electric Power Research Institute, and other manufacturers. The main competitors in the local and county dispatching markets include Guodian Nari, Dongfang Electronics, paneng technology Jicheng electronics and other manufacturers

for the substation automation system with voltage level of 110 kV and below, at present, hundreds of domestic enterprises are engaged in the R & D and production of this product. The competition among manufacturers is mainly reflected in the R & D strength and manufacturing level of software and hardware of the system. From the perspective of enterprise scale and competitive strength, the main manufacturers participating in this part of market competition in the power system, in addition to paneng technology, which was the first to launch substation integrated automation products integrating protection and telecontrol monitoring functions in China according to the user needs of local and county-level power supply companies, there are also Guodian Nari, Nari Jibao, Guodian Nanzi, XJ electric, Dongfang Electronics and other manufacturers, The market share of this field in the power system is mainly shared by them. In the substation automation market with voltage levels of 110 kV and below in the power system, these companies have formed a basically stable competition pattern, accounting for more than 80% of the domestic market share, and the entry barriers of new manufacturers are relatively high

the operation conditions of industries outside the steel, petrochemical, coal and other systems are relatively complex, and the requirements for power supply quality, power safety and stability are relatively high. Therefore, there are many new requirements for power automation products, such as strong technical applicability of products, close technical support of manufacturers, etc. Because the technical standards of this market are not unified, and they belong to different industries, they are less affected by the power sector, the product demand varies greatly, there are more non-standard projects, and large protection manufacturers are unwilling to intervene too deeply, which leaves a large space for many small and medium-sized equipment manufacturing enterprises. At present, this part of the market share is mainly occupied by Panneng technology, Guodian Nanzi, Wanlida, DeWitt and other manufacturers

at present, the manufacturers with completely independent intellectual property technology in the field of microcomputer relay protection, substation automation and high-end application software of power automation in recent years include Guodian Nari, Dongfang Electronics and paneng technology. The coordinated development of relay protection devices and power automation control systems enables these companies to maintain a leading position in science and technology in the industry, and can smooth the fluctuation risk of the industry by regulating production. Take Panang technology as an example, Its product Gerry said: "Then it can be diluted to an appropriate concentration according to the required mechanical properties. It has become one of the mainstream products in the field of relay protection and control of power system. It has strong market competitiveness, can fully share the huge market of power automation industry, and has broad development prospects. At present, there are about 1500000 microcomputer protection devices and thousands of dispatching automation systems in the power system and its users. If the microcomputer relay protection is in service The number of protective devices and the number of substation automation put into operation are ranked. In the relay protection and substation automation industry, Nari relay protection, Sifang relay protection, Guodian Nanzi, XJ electric, Guodian Nanrui, Shenzhen Nanrui, Dongfang Electronics, paneng technology, Jinzhi technology, Wanlida, etc. can enter the top ten. In the field of dispatching automation, Guodian Nari and Dongfang
