变电站数字化改造的经济性分析

Economical Analysis of Digital Remake of Transformer Substations

数字化变电站是目前国内电力系统建设的一个热点,但是,国内目前数字化变电站的研究和实现都热衷于新建一个数字化变电站,而没有关于已有老变电站数字化改造的研究.但在美国等发达国家,因为很少再造新的变电站,所以如何对已有的变电站进行数字化改造成为重要的课题,本文分析了变电站数字化改造的相关技术,并进行相应的经济性分析,可为我国变电站的数字化改造提供重要的决策依据.

Digital Substation is currently a hot issue of electric power system construction, but the current topic of the domestic research and implementation of substations is keen on the construction of a new digital substation, rather than doing the research on the digital remake of old substations. However in the United States and other developed countries, because of very few new substations, how to digitize the existing sub- station has become an important issue. This paper analyzes the technologies of the digital remake of substations, and the corresponding economy, which makes an important basis for making decision.
