上海大容量火电机组黑启动系列试验

上海电网发电系统是以纯火电为特征,且大容量机组占绝对优势,对于机组黑启动而言,这些均是劣势。通过一系列黑启动试验及其研究,解决了长期以来一直困扰上海电网的缺乏黑启动能力的问题。本文通过介绍上海电网黑启动系列试验的总体过程和主要结论,分析了燃气轮机作为黑启动电源、全压启动大容量变压器、燃机小系统带重负荷长期稳定运行等上海电网黑启动试验的独特之处。

A Series of Blackstart Tests Based on Gas Turbine Generators in Shanghai Power Grid

In accordance with the principle of progress step by step, a series of blackstart maneuvers were conducted in Shanghai power grid during the period of one year. The feasibility of the blackstart scheme for Shanghai power grid was verified by these tests adequately, and the effectiveness of both organizational work and technical measures adopted during the blackstart process was examined. Here, the overall process and main conclusions of the serial blackstart tests in Shanghai power grid are presented, and the distinctive features of the blackstart tests in Shanghai power grid, such as using gas turbine generators as the power source of blackstart, starting high-capacity transformer with full voltage and long-term stable operation of a small system with heavy load supplied by gas turbine generators, are emphatically described.
