一种新型智能低压无功补偿装置的设计

针对传统无功补偿装置的特点，提出了一种以LPC2388处理器为核心、功率因数和无功功率为控制量，同时考虑电压因素的新型智能低压无功补偿装置。该装置能够实现电容的零电压导通和零电流断开的“零投切”功能，可以根据具体的补偿方式和无功功率的大小，选择需使用智能无功装置的类型和数量。该装置体积小、成本低、应用灵活、组网方便，有广阔的应用前景。

Design of a New Intelligent Low Voltage Reactive Power Compensation Device

In view of the characteristic of the traditional reactive power compensation devices, a new intelligent low voltage reactive power compensation device based on LPC2388 processor was proposed, which taked the power factor and reactive power as the controlling quantity while considering the effect of voltage. The device could achieve the functions of zero-cross switching of capacitor, including turning on the switches while the voltage was zero and turning off the switches while the current was zero. Users could choose the type and quantity of this device, according to specific compensation mode and reactive power. With the advantages of small size, low cost, flexible application and convenient organizing network etc, the device has broad application prospects.
