新型高精度无功功率发生器的研制

为了衡量无功补偿控制器的实际补偿效果,传统上采用可调的电感、电容、电阻等负载来模拟.这种方法浪费能源、控制精确度差、使用上也给用户造成不便.为了克服这些缺点,本文设计了采用单片机智能控制的新型无功功率发生器,该方法提供独立的电压和电流输出,能模拟较大容量的无功功率输出,节约了能源.同时,本文给出一种改进的数字比例调节器,实现了控制精度的大幅提高.高精度、小巧以及良好的人机界面都给使用带来了极大的方便.

Development of novel reactive power generator with high precision

It is essential to promote the energy efficiency,control precision and usage convenience of the traditional simu- lative reactive power generator that utilized simulative load.In order to achieve these goals,a novel simulative reactive power generator was proposed,which employed the advanced singlechip and algorithms.The generator provided the independent voltage output and current output to simulate active and/or reactive power.This kind of architecture can largely save the en- ergy during experiment and measurement.A modified digital P regulator is developed to improve the voltage and current precision.A human-machine interface with high precision which is smart and better brings great convenience to users.
