异步化同步发电机运行控制的关键是转子励磁的控制,该文论述了异步化同步发电机定子磁场定向控制的原理,讨论了定子磁场定位和转子位置的确定方法,转子励磁采用易在DSP中实现的模糊PID控制,并研制了DSP转子励磁控制装置,进行了异步化同步发电机转子励磁模糊PID控制的试验研究。试验结果表明,异步化同步发电机采用模糊PID控制策略是有效的,不但能够实现有功功率和无功功率的独立控制,而且具有良好的静态调节特性和动态特性。

Fuzzy PID Control of Rotor Current Excitation in an Asynchronized Synchronous Generator

The theory of rotor flux oriented control of an asynchronized synchronous generator is investigated.The methods to determine the stator flux and the rotor position are discussed.The fuzzy PID control,easily complemented in digital signal processor(DSP),is applied to the rotor current excitation.An alternating current excitation device based on the DSP is constructed and the tests of rotor exciting current fuzzy control are developed.The experimental results demonstrate that the fuzzy-PID controllers are effective.Not only that the active power and reactive power can be controlled independently,but also the controllers can improve the dynamic performances of the generator.
