Research On Intelligent Transformation Scheme Of 500kV Wang Dian Substation

With the development of new technology and intelligent equipment,the intelligent transformation of conventional substation has the necessity of technical promotion,and the smart grid is considered as an effective solution to the development of power grid.In this paper,through the research of the intelligent substation,analyze the location with Wang Dian variable transformation,and the national grid relevant countermeasure,given the transformation process of the project,and combined with the transformation of the former a part of the equipment problems need to be combined with the transformation of the project;gives the principle of power transformation in the transformation,and analyzes the characteristics of.In this paper,describes the monitoring running state of the equipment in the transformation of the background,in the premise of not easily cut under the new and old monitoring system must satisfy the switching operation and accident handling requirements,proposed the use of virtual instrument device to realize the old system to the new system of data transmission scheme,and the scheme through the transformation of the new dual equipment the position of node output inline locking function of the old system,finally realizes the equipment by power outages,does not affect the operation of power grids,to steadily push forward reform.In the relay protection part of the transformation,the current configuration of the substation protection combined with the ultimate goal of reconnaissance,protection and rebuilding,the paper puts forward the protection of different transformation schemes,and through the comparison of various schemes of safety,construction volume,the time of power cut,clear the best scheme,provides reliable support the measures for the smooth implementation of the final project,provide a reference for future intelligent transformation of other conventional substations.In this paper the integration of AC and DC transformation section,the author through to the present substation in operation to field investigation of DC system,the existing problems were analyzed,each subsystem of whether the transformation provides a clear basis,and make two kinds of scheme design for the DC system transformation,through comparative analysis,are more in line with the solution for the safe operation of power grid,lay the foundation for the smooth implementation of safety engineering.
