关于改进天津白庙变电站站控层网络结构的研究

Study on improving the network structure of station level in Baimiao transformer substation

变电站自动化是一项提高变电站安全、稳定和可靠运行水平,降低运行维护成本,提高经济效益,向用户提供高质量电能的一项技术措施。站控层网络结构是变电站综合自动化的关键。本文分析了天津白庙变电站自动化系统中站控层网络结构存在的问题,同时从该站的实际情况出发给出了四种改进方案,并对这四种方案的优缺点进行了详细的分析比较。最后,经过讨论得出了适合该变电站的最佳改进方案。

The definition of transformer substation automation is a way, which can make it work more safely, stably and reliably. It is also a technology that can debase the cost of operation, improve the benefit of economy and supply high quality electricity to the users. The network structure of station level is a key in substation automation system. In this paper, the problems of network structure in automation system of Baimiao, Tianjin are presented. Moreover, four schemes to improve the capability of automation system are given and all of them are based on current situation in the substation. The advantages and disadvantages in the four schemes are analyzed in detail. In the end, the prime scheme is proposed according to the analysis.
