摘要:
在低压电力系统中，无功功率作为影响电压稳定的一个重要因素，对其实现有效补偿是确保电力系统安全高效的必要措施。该文以济宁某煤矿的实际需要为应用背景设计了一种基于FFT的低电压无功功率自动补偿控制器。该控制器以ARM处理器为核心，运用FFT算法计算得到功率因数、相位差等电参数，为电容投切提供依据。经Simulink仿真表明应用该算法能够准确有效得到相应电参数，进而实现无功补偿。该控制器已投入使用，在煤矿井下供电系统中运行良好，能够有效补偿电网中的无功功率，为煤矿提高了经济效益。
Abstract:
In low voltage power system, reactive power is an important factor affecting voltage stability, and effective compensation for it is a necessary measure to ensure the safety and efficiency of power system. In this paper, a low voltage reactive power automatic compensation controller based on FFT is designed for the practical needs of a coal mine in Jining. The controller takes the ARM processor as the core, and uses the FFT algorithm to calculate the power factor, phase difference and other electrical parameters, which provides the basis for the capacitor switching. The simulation of Simulink shows that the application of the algorithm can accurately and effectively obtain the corresponding electrical parameters, and then the reactive power compensation can be realized. The controller has been put into use. It runs well in the coal mine underground power supply system, it can effectively compensate the reactive power in the power grid, and achieve better economic benefits for the coal mine.
