Aiming at the features of grid - connected pv system , a kind of grid - connected control strategy is presented , which is based on the multi - variable double - loop control and synchronization phase - locked control . the multi - variable double - loop control is used for the real - time tracking , and the inherent principle error existing in the single - loop control is eliminated . the synchronization phase - locked control makes the frequency and phase of output current equal to those of utility voltage
针对光伏并网的特点，本文提出了一种基于多变量双环控制与同步锁相控制的并网控制策略，多变量双环控制用于电流的实时跟踪，解决了只采用单环控制存在的原理性误差问题；同步锁相控制则保证输出电流与电网电压同频和同相。
