大容量调速抽水蓄能发电系统是运用最新电力电子技术在电力系统中应用的一种新型发电系统。这些新型发电系统不仅可以通过控制转子转速来改变输入功率来实现夜间电力系统的频率调节，还可以通过快速控制电压和功率来增强电力系统的稳定性。为了支持电力系统稳定器的设计，提出了一种基于扩展Heron-Phillips模型的分析方法，用于提高可调发电系统附近同步发电机的动态稳定性。以数值算例说明了基于新解析方法的系统方法，说明了如何构建电力系统附加稳定控制器和可调发电系统主控制器。
Adjustable-speed pumped storage generating systems of large capacity have been newly installed in power systems with recent technologies of power electronics. These new generating systems contribute not only to frequency regulation of power system at night by means of input power change as results of rotor speed control, but also to enhancement of power system stability by fast control of voltage and power. New analytical method based on extended Heron-Phillips model was developed in order to support designing of power system stabilizer which is used to improve dynamic stability of the synchronous generators located in the vicinity of the adjustable-speed generating system. Systematic approach based on the new analytical method is shown with numerical examples, explaining how to construct the additional power system stabilizing controller as well as main controller of the adjustable-speed generating system.
