电力系统配电网可靠性与经济性问题研究

Research on Reliability and Economy of Power Grid

配电网处于整个电力系统的末端,配电网的可靠性直接影响到用户的使用,与用户直接相关联。长期以来,配电系统的可靠性都备受关注。为了更好地保证配电网的可靠性,很多国家都在研究配电网的评估模型。另外,配电网在整个电力系统的投资中占了大约六成,所以,配电网的经济性也是必须要考虑的问题。本文首先对配电网可靠性经济进行分析,然后简单介绍了影响配网可靠性的因素,以及一些应对措施。

Distribution network is at the end of the whole power system. Distribution network reliability directly affects the power use of user, and relates directly to the user. For a long time, power distribution system reliability is concerned. In order to guarantee the reliability of the distribution network, many countries are studying the distribution network assessment model. In addition, the investment of distribution network accounted for about sixty percent in the investment of whole power system. Therefore, the distribution network economy must be considered. At first, this paper analyzes the distribution network reliability, and then introduces the influencing factors, as well assome measures.
