摘要: 分析了机组正常运行期间电力系统稳定器(PSS)出现频繁投退以及长时间退出的原因,结合PSS功率自动投退的实现逻辑及影响燃煤机组运行工况的3方面因素,提出一种适合于燃煤机组PSS功率自动投退定值的整定方法。以某1 000 MW燃煤机组为例,优化整定了该机组的PSS功率投退定值,优化后的PSS能消除频繁投退及长时间退出现象。该方法简单实用,适合工程化应用。

Abstract: This paper analyses the causes of the power system stabilizer (PSS) frequent act and return as well as long-term offline during the normal operation of the coal-fired units. Taking the logic of PSS power automatic action and return and the three factors affecting the operating condition of the coal-fired units into account, the paper proposes a method of setting value tuning that is suitable for coal-fired units’ PSS power automatic action and return. By using this method, the PSS action and return setting values of a 1 000 MW coal-fired unit are optimized. The optimization is able to eliminate the PSS frequent act and return and long-term offline. The result shows that the method is easy to practice and applicable in the industry.

Key words: coal-fired unit, power system stabilizer (PSS), action value, return value, tuning method
