浅谈安全稳定控制装置在长洲水电厂实际应用

Discussion on the Application of Security and Stability Control Equipment in Changzhou Hydro-complex

随着电网的发展和扩大、输电线路电压等级的提高和远距离大功率的输电方式出现,电网结构复杂、联系紧密,对系统的安全稳定运行提出了更高的要求,系统除了要建立一个结构合理且联系紧密的电网来满足电网安全稳定运行的要求之外,还需要配置电网安全稳定控制装置。安全稳定控制装置是作为保持电力系统安全稳定运行的第二道防线的重要设施,笔者以长洲水电厂内江站、外江站、苍梧站各配置的一套安稳系统为例浅析了安全稳定控制装置在长洲水电厂的实际应用。

The power grid requires a system with higher safety and reliability with the extension of power grid, the increasing voltage class of transmission lines and the development of transmission lines of long distance and high power rating. Except for establishing a power grid system with reasonable structure, the system requires a security and stability control equipment as the second defense to maintain the safe and stable operation of the system. Taking Changzhou hydro-complex as an example, the paper briefly analyzes the practical application of the security and stability control equipment.
