Abstract

本发明涉及一种高压双馈发电系统中网侧变流器直流电压的控制方法，其包括以下步骤：1)电网电压处于正常工况时，通过电流内环和直流电压外环实现对网侧变流器直流电压的控制；2)对电网电压是否稳态抬升进行判断；如果电网电压不稳态抬升，则执行步骤3)；如果电网电压稳态抬升，则通过重新确定合适的直流运行电压U'dc_ref和Chopper组件的工作电压，采用与步骤1)相同的控制过程实现对变流器网侧直流电压的控制；3)对电网电压是否出现暂态变化进行判断；如果电网电压未出现暂态变化，则控制过程结束；如果电网电压出现暂态变化，则通过电流单闭环实现对网侧变流器直流电压的控制。本发明可以广泛应用于对变流器网侧直流电压的控制中。
