摘要
电力电子变压器(PET—PowerElectronicTransformer)是一种新型的电能转换设备,它通过电力电子变换技术实现电力系统中的电压变换和能量传递。研究了PET在电力系统中的控制问题,提出了在单机无穷大系统中与发电机相连的PET的控制策略,并在MATLAB环境中进行了时域仿真研究。仿真结果表明,在系统中出现扰动的条件下,PET能有效的提高系统阻尼,改善系统电压特性,提高了电力系统的稳定性。
Power electronic transformer (PET) is a new type power transmission device, which realizes voltage transformation and power delivery through power electronic conversion. In this paper, a new PET control strategy based on single-generator infinite system is presented. Simulations based on MATLAB/Simulink are carried out, and the results show that the proposed controller can improve the system stability effectively under different disturbance.
