Study on Setting Value Tuning of PSS Automatic Power Action and Return for Coal-Fired Units

doi:10.11930/j.issn.1004-9649.201608118

Abstract

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
