摘要
本文介绍了一种利用可控硅的无功功率补偿装置。分析推导了无瞬态，零电流接通条件。分析了主电路以及控制电路的工作原理。由于采用可控硅，保证电容器组在投入时无冲击，无振荡。该系统在“徐州轮”上实用证明，系统反应快速，工作可靠，补偿效果显著，可使功率因数由0．1～0．3提高到0．8～0．9，有效地提高了船舶电站的安全可靠性、经济性和电能质量，具有很高的实用价值。
In the paper a SCR reactive powcr auto-cornpensation device is intreduced. The conditiom of non-instantaneous state and ze ro current when switching on is analyzed and derived. The working principles of the main and the controlling circuit are also analyzed.For SCR is adopted, it may be insured to put the capacitor-group into work without any impact and oscillation. The practical opera tion on ship 'XUZHOU' shows that the device can respond very quickly and work reliably, its compensative effect is remarkable (the power factor may be inereased from 0. 1~0. 3 to 0. 8~0. 9). It is of high availability for it can effectively heighten the reliability, the economy and the electrical energy quality of the electric power station on ship
