Electric power automation technology development present situation .
Electric power automation system is the use of advanced computer technology, modern electronic technology, communication technology and information processing technology of substation secondary equipment (including relay protection, control, measurement, signal, fault wave record, automatic device and remote device, etc.), optimizing design, the function of implementation for the operation of all equipment in the substation monitoring, measurement, control and coordination of a kind of comprehensive automation system. Each device in the integrated substation automation system by exchanging information between, data sharing, substation operation monitoring and control task. Substation integrated automation replaces conventional substation secondary equipment, simplify the substation secondary wiring. The safe and stable operation of substation integrated automation is to improve the substation level, reduce the operation maintenance cost, improve the economic benefit, to provide customers with high quality is an important technical measures of electrical energy.
From the 1960 s began to development of substation automation technology in our country. To the early 70 s, it has successively developed the electric centralized control and protection, control and signal for the integration of device. In the mid - 80 - s, developed by tsinghua university, 35 kv substation of microcomputer protection, substation monitoring automation system in weihai at island in operation. Meanwhile Beijing nanjing automation research institute has developed a 220 kv mei mouth of substation integrated automation system. In addition, the domestic many high schools and scientific research units are also done a lot of work in this aspect, some different types, different function of automation system. For the development of the domestic substation automation technology played an effective role.
Into the 90 s, the substation integrated automation has become a hot topic, research units and products such as spring up, a representative of the company and the products are: Beijing sifang company CSC 2000 series integrated automation system of nanjing south group company BSJ2200 computer monitoring and control system, the nanjing south relay protection electrical co., LTD the RCS of a 9000 series integrated automation system, since PS series 6000 integrated automation system ranks, Xu Ji electric CBZ a series 8000 integrated automation system and Wu Hanguo GCSIA substation integrated automation system, south red DSA substation integrated automation system between urban and rural areas, Xu Ji electric company of CBZ series 8000 integrated automation system.
Today because of the microprocessor and the rapid development of communication technology, the technical level of substation automation system has improved more, structure system constantly improve, now of the substation automation system, it is the station spacing layer devices (including the microcomputer relay protection and automatic device, the measurement and control, dc system, etc.) in the form of interconnection and the host to realize data exchange and processing, so as to constitute a service in grid security and monitoring control, distributed, and can operate fully digital automatic control system. In all of the emergence of distributed automation system for the system provides a wider choice. With the increasing of the substation automation system applications, whether it be a building, expanding or technical renovation project, strive to simplification and standardization in the selection of substation automation system. Substation automation not only mature technology, and the product is complete, the price is also more and more low, the selectivity of system products, scalability and applicability is becoming more and more good, also for application in the power system and by the implementation of the power automation enterprises laid a solid foundation.
