Application Research Microcomputer Protection Of Zhaocun Substation

With the development of computer technology in power system applications , an increasing number of new integrated automation substation design, but there are still a large number of conventional substation, the substation is generally the hub of power grid substation, the capacity of large, round, a device aging, damage and corrosion serious maintenance updated increasing workload and costs, and the safety of the substation, high-quality, pose serious threats to efficient operation of power grid system security, stability, optimal operation is also a hidden danger . Therefore, the type of substation to carry out a reasonable, economic, and advanced transformation possible, and fewer people on duty to meet the requirements, has become part of our power systems engineering and technical personnel of the pressing issues currently facingFirst of all, Zhaocun 110kV substation microprocessor-based protection of the status of the investigation and analysis, combined with the actual operation of the status quo, to study the subject of microprocessor-based protection substation background and basic theory, to clarify the issue of the necessity and feasibility study.Secondly, for Zhaocun change the actual situation of a microprocessor-based protection of its transformation program design, the secondary system of ZXS10 ZTE substation integrated automation system, combined with its practical operation in the substation Zhaocun appeared in several issues described, respectively, proposed solutions.In addition, in 2009, I planned substation microprocessor-based protection of Zhaocun upgrading again, at the same time for five conventional substation transformation of microprocessor-based protection. Therefore, this article from the program selection, parameter tuning, installation and operation and maintenance of such areas as the transformation of the substation automation design a program with a very strong practical significance.Finally, live debugging, microprocessor-based protection screen and put into operation to observe the operation of the circuit parameters, and determines the flow of communication lines, the time it should respond to meet the requirements of the background of real-time data acquisition, graphical curve, Report Generator, the authentication device modified the operation of microprocessor-based protection situation.
