Application Research On Microprocessor Protection And Monitoring System Of The 6kv Substation And Their Technical Reconstruction

Integrated substation automation substation secondary equipment is through a combination of functionality and optimized design, the use of advanced computer, communications and signal processing technology to realize the major substation equipment and transmission and distribution lines, automatic monitoring, measurement, microprocessor-based protection, as well as scheduling and communications integrated automation. Substation integrated automation system to replace or update the traditional substation secondary system, power system has become one of the major trends. The topics to Zhongyuan Oilfield Petrochemical 6KV distribution of the second part of the protection and monitoring as the research object, there is protection against the low reliability, poor performance measurement monitoring the situation, through the microprocessor-based protection device studies, worked out following the electrical protection, the mother prepared in conjunction computer program from the cast. Meanwhile, in the event of power quality disturbance event, analyze the causes of the incident and to develop response measures.By Zhongyuan Oilfield Petrochemical 6KV distribution of the second part of the protection and monitoring of the status of investigation and analysis, combined with its actual operation status, study subjects substation integrated automation system background and basic theory, clarifying the need for this research project nature and feasibility. Pairs of transmission line-stage current protection, automatic re-closing devices such as the basic principles are described. Combined substation integrated automation system technology-related content, right 6KV Substation Integrated Automation System of the composition was analyzed. 6KV distribution for the actual situation and to carry out a comprehensive reform program of automation system design, selection of type SEL-351A Feeder Protection Systems, SEL-2020 Communications Processor and other products, has established substation overall system model, and separately over several devices on its principles, functions, features and installation of an introduction and notes.After on-site commissioning, put into operation, real-time observation of the circuit operating parameters, determines the flow of communication lines, the time to respond to it to meet the requirements, background real-time data acquisition, graphical curve, fault recording, report generation, and hence verify the second part of the post-transformation protection reliability, monitor performance measurement and so on.
