新疆南部电网安全稳定控制系统由安装在30个厂站的稳定控制装置组成,覆盖巴州、阿克苏、喀什、和田地区。当新疆南部区域电网联络线或主力机组发生故障时,采取解列、切负荷措施,防止大面积停电,保证新疆南部电网的安全稳定运行。文中通过对新疆南部电网安全稳定控制系统的研究,提出了适合于该类型电网的稳定控制系统结构、实现方式、新原理、新判据。该系统多次在电网故障中正确动作,确保了电网的稳定运行。 The safety and stability control system of the southern Xinjiang Power Grid is composed of the stability control devices installed at 30 plant sites covering the areas of Bazhou, Aksu, Kashgar and Hotan. When the southern Xinjiang regional power grid contact line or the main unit fails, to take off, cut the load measures to prevent large-scale blackouts, to ensure the safe and stable operation of the southern power grid in Xinjiang. Through the research on the security and stability control system of southern Xinjiang Power Grid, this paper presents the structure, the realization method, the new principle and the new criterion of the stability control system suitable for this type of power network. The system repeatedly in the grid fault in the correct action to ensure the stable operation of the power grid.
