中文摘要:
      针对传统九区图控制法存在的“投切震荡”和“操作频繁”等问题,结合模糊控制理论设计了一个改进的基于模糊控制的工厂低压无功补偿控制器。该模糊控制器采用两输入单输出结构,以电压偏差和无功偏差为控制量,以无功功率补偿量为被控制量,选用三角形隶属度函数。为了验证该模糊控制器的可行性,在MATLAB中建立了基于该控制器的无功功率补偿模型。仿真结果表明该设计的模糊控制器是可行的,解决了投切震荡等问题,提高了系统准确性,从而改善电网质量。
英文摘要:
      In this study, a improved controller, aiming at “swing of plug in and take away of capacitor” and “operating frequently” of the traditional nine zone control method and combining the fuzzy control theory, based on fuzzy control is designed which fits for low voltage reactive power compensation of factories. This fuzzy controller adopts two input and single output structure, with voltage deviation and reactive power deviation as the control variables. The reactive power compensation is the controlled variable, and the triangular membership function is selected. In order to verify the feasibility of this fuzzy controller, a reactive power compensation model based on this controller is established. The simulation results show that the proposed fuzzy controller is feasible, which solves the problem of switching vibration, improves the accuracy of the system and improves the quality of the power grid.
