模糊PID技术在水电站计算机监控系统中的应用

Application of fuzzy PID technology in hydropower plant computer monitoring system

在诸多的发电形式中,水力发电因环保、节能等特点成为电力工业的一个重要组成部分。水电站是依靠大坝的来水量进行发电的,这使其具有极大的不确定性,导致水轮发电机运行的不平稳,这不仅会影响发电机寿命,还会破坏电网的稳定,影响电能质量。为了解决以上问题,在机组控制程序中加入了模糊PID控制器,为水轮发电机提供了良好的动态和静态性能。

In many forms of electricity generation, hydraulic power with environmental friendly and energy- saving features was an important part of power industry. Hydropower station was rely on the dam water for power generation. This factor was of great uncertainty, would lead to instability of the hydraulic generator. The life of generator was influenced. The stability and quality of the power system were damaged. In order to solve the above problems, a fuzzy PID controller into the unit control program was put forward; good dynamic and static performance of turbine generator was provided.
