该系统能够同时模拟频率类、电压类、电流类等多种信号，还能同时检测电子仪表的精度。

The system can be used to analog signals of frequency, voltage, current simultaneously etc. Meanwhile it can be used to detect precision of the meters.

结果表明谐波及无功检测信号只不过是电容电压闭环系统中的一个前馈补偿信号，其存在不但不能提高反而影响谐波及无功的稳态和动态补偿精度。

It is concluded that the harmonic and reactive current detection behave as just a feed-forward signal in this closed-loop, and it is incapable of improving the compensation accuracy in steady-state.
