The Intelligent Transformation Of 110 Kv Guishan Substation

110 kv substation guishan although adopted some substation automation technology, improve the technology of power grid operation, improve the ability and reliability of the substation automation control, but still maintain the original conventional substation automation system function and the logical relations, the product of different manufacturer can’t exchange, data interaction is restricted, affected the substation investment, operation and maintenance, it is necessary to carry out the intelligent transformation.This topic according to the requirements of the substation intelligent technology, analyzes the existing substation and running situation, determine the retrofit scheme and main technical points; On this basis, the first by changing and upgrading, to conventional modification of a device, on the one hand, increasing the number of \"intelligent control\" function, realize the isolation knife switches far remote control function, improve the security and reliability of personnel and equipment, on the other hand to establish intelligent component implementation of an equipment state of measurement, control, measurement, monitoring, protection, and other functions; Followed by automation system, its core lies in DL/T860 (IEC 61850) standard system, process layer to solve the traditional digital substation secondary wiring cable complex, poor anti-jamming capability, poor system scalability shortcomings, realize information sharing, is programmed control, the secondary equipment state overhaul mat foundation, according to the specification and guideline requirements and modification of structure of automation system, the integration information platform and configuration tools, between substation and control center at all levels of \"plug and play\" function, to reconfigure the relay protection and automation system equipment, but also add the sequence control function, prevent false atresia, the basic function such as network packet records analysis function; Again is to increase the intelligent substation advanced application functions, including intelligent alarm function, fault information comprehensive analysis decision and analysis and decision function; In addition, to stand with the power supply and auxiliary system for the intelligent transformation, transforming part of older power equipment, improve equipment reliability, realize the total power equipment centralized arrangement, communication power supply, UPS power supply comprehensive monitoring, and increase the dc feeder circuit, according to the practical situation in terms of auxiliary system, in order to meet the requirements of the unattended substation, the video monitoring, security, fire and other subsystems.Modified,110 kv substation guishan become based on DL/T860 (IEC 61850) standard system adopts hierarchical distributed structure, total station master device to realize state visualization, real-time monitoring of equipment, a unified information platform, standing with integration, an intelligent control equipment, has the function of anti false atresia, sequence control function and a series of basic functions, at the same time has the fault information comprehensive analysis, intelligent alarm analysis of advanced application functions such as intelligent substation.
