Workless power is an important factor in designing and running of alternating current system. A compensation device is needed in substation and the end users to save electricity.
无功功率是交流电力系统设计和运行中的一个重要因素，为了减少电能损失，需要在电力用户端与电力系统的变电所内合理配置一定的无功补偿装置。
The system generates a direct current, so using it to power DC devices locally is more efficient than switching to the alternating current needed to feed it back to the grid.
该系统产生的电流为直流电，所以用来驱动本地的直流点装置比将其转化为交流电输入电网来的更有效率。
In the knowledge system of alternating current, the restrictive relationships of some physics quantities are similar with those of mathematical Numbers.
