摘要
柔性交流输电系统(FACTS)技术在提高电力系统运行稳定性和用电效率等方面起着至关重要的作用,即在FACTS技术的基础上对静止同步串联补偿器(SSSC)的数学模型和控制技术进行研究,并试将其应用到中低压电网中。先对配电网串联补偿装置的拓扑结构和控制技术的仿真模型再到小型模拟实验调试进行了深入细致研究,最后设计了以DSP+CPLD为核心芯片的模拟串联补偿装置控制系统,该串联补偿装置的控制系统是基于静止同步串联补偿器(SSSC)在配电网中的应用,它可以改变系统电压、电流、相角等参数来提高电力系统运行的稳定性。经Matlab仿真对配电网系统模型的分析和实验室对小型串联补偿装置控制系统的波形验证结果观察,该串联补偿装置控制技术可行,其对动态的无功补偿大大地提高了电网的功率因数,使串联补偿装置的控制系统性能得到了极大地提高。
The technology of FACTS plays an important role in improving the stability of power system and the electrical efficiency etc. On the basis of FACTS, the mathematical model and control technology of SSSC are researched and applied in the low voltage power grid. Firstly, the simulation mode about the topology structure and control technology of series compensation device of distribution network are built. Next, small simulation debugging experiments are researched carefully. Finally, by using DSP-CPLD as the core chip, analog control system of series compensation device is designed, which is based on the application of SSSC in the distribution network and can change the voltage, electric current, phase angle and other parameters to improve the running stability of power system. The distribution-network system model is analyzed by Matlab and the waveform results of small tandem compensator control system observed in lab demonstrate the feasibility of this control technology. Because of the dynamic reactive power compensation, this technology improves the power factor of power grid and the control system performance of series compensation device largely.
