Although China's capacitor technology has been improved, but the power capacitor manufacturing enterprise product structural problems and integrated technical weaknesses, is still not well resolved. After years of development, China's power capacitors manufacturing process, equipment and technology have entered the ranks of the world's most advanced. However, due to China's power capacitor manufacturing enterprises there is a great development of manufacturing technology and the development of the power system phase out of the question, which will lead to 500 kV and 220 kV substation with large capacity parallel capacitor compensation device with the main wiring inappropriate, Improper and accessories selection and parameters with the problem of improper.
In recent years, the State Grid Corporation of scale implementation of bidding, to help solve the capacitor capacitor capacitor industry, the problem of configuration confusion, while the power capacitor industry to determine the direction of development. In addition, the standard bidding to correct the high-capacity capacitor group wiring error rate is too high to solve the large capacitor with the relay protection and setting calculation problems, and large capacitor group blasting energy exceeded the problem. From the power system operation statistics, with the solution of these problems, the reliability of the reactive power compensation device is also increasing year by year, the explosion of the large capacitor group has been a significant decline in fire accidents trend. However, despite the capacitor technology has been improved, but the power capacitor manufacturing enterprise product structure problems and integrated technical strength is weak, still not well resolved.
Training comprehensive technical personnel
With the increase of the transmission capacity of the power grid, the requirements of the capacity of the capacitor bank also increase, and the harmonic problems, noise problems, equipment problems, security and reliability problems are becoming more and more prominent. Therefore, in considering the production, design, and optimize to solve these problems, will be the most economical and reasonable approach. Otherwise, the product runs in the problem and then to transform the product, whether human, material, financial costs are much greater than the design and manufacture of the cost of investment. But also solve the problem of the effect, but also far worse than the design and manufacturing stage. Therefore, this concept is the most effective energy-saving measures in the design phase, that is, the overall consideration of all factors, targeted design and manufacturing, so that the concept of resource consumption to a minimum. To do this, the manufacturing industry technical staff not only familiar with their product manufacturing technology, and must be familiar with the product conditions of use, power system operation requirements, equipment access to the surrounding environment, other equipment on their own products Impact and other aspects of technology. Only in this way, the products can be designed and manufactured with the environment to achieve a good compatible state, get a good safe operation of the reliability.
The current power capacitor manufacturing enterprises a serious lack of comprehensive technical personnel, power capacitor manufacturing enterprises to appear although the assembly of world-class plant, equipment, but the products did not reach the world advanced level of the phenomenon of synchronization. Therefore, the cultivation of integrated technical personnel, is the power capacitor manufacturing enterprises one of the development strategy.
The development of diversified products
The scale of manufacturing enterprises is relatively small, single product structure is the common phenomenon of China's power capacitor industry. In fact, the reactive power balance is one of the objectives of the power system to run well. The realization of this goal involves the distribution and control of reactive power flow, the adjustment and control of node voltage, the switching and control of reactive power compensation equipment, the switching and control of load size and so on. Capacitor device is only one series of reactive power compensation equipment. It can be predicted, as another type of reactive power compensation device - power electronic reactive power compensation device, in the current rapid development of the situation, the resulting reactive power compensation function, will become increasingly strong, and the price will be more The lower. This impact on the capacitor industry will not be too long. Therefore, the power capacitor manufacturing enterprises should be in the current good market atmosphere, pay close attention to product structural adjustment, transfer to the direction of new products. At the same time, speed up the technical reserves, which is the long-term healthy development of reactive power compensation technology is the best guarantee. Will promote the development of capacitors.
