摘　　要：独立电力系统电压的稳定性主要取决于柴油发电机组的电压响应特性。同步发电机调压系统是一个非线性控制系统,为了分析系统的动态特性,首先建立同步发电机调压系统的非线性数学模型,然后以此为基础设计状态反馈H2/H∞调压器。将H2/H∞控制理论应用于柴油发电机组调压器的设计,把系统性能要求转化为标准H2/H∞控制问题,获得了柴油发电机组状态反馈H2/H∞电压控制律。计算机仿真结果表明,设计的状态反馈H2/H∞调压器有效地提高了系统的动态精度和抑制扰动的能力,改善了独立电力系统电压的稳定性。The voltage stability of an isolated power system is determined by the voltage response characteristic of diesel-generator set. The synchronous generator voltage regulation system is a nonlinear control system. In order to analyze the dynamic characteristic of the system, a nonlinear mathematical model of synchronous generator voltage regulation system is built first, and a state feedback H- two/H-infinity voltage regulator is designed on the basis of this. The H-two/H-infinity control theory was used to design the diesel-generator set voltage regulator, which transforms the specifications of the system into a standard H-two/H-infinity control problem, then a state feedback H-two/H-infinity voltage control law of the diesel-generator set was achieved. The computer simulation results show that the state feedback H-two/H-infinity voltage regulator improves the dynamic precision of the system and the ability of restraining the load disturbance, thus improves the voltage stability of an isolated power system.
