摘　　要：为解决建筑电气设备电源频率的调控切换问题,本文提出一种基于PI调节器的电气设备电源频率自动调控方法,该解决方法的创新性在于PI调节具有较强的鲁棒性,维持系统稳态的同时,还能在出现偏差时产生控制作用,以保持系统稳态。本文在MATLAB软件中搭建了排风系统,仿真结果表明:所提方法能够控制独立电源电稳处于1s以下,可实现三相与单相交流侧的电稳控制在0.02s和0.11s,具有较高的自动快速调控能力。In order to solve the problem of frequency control switching of power supply under building electrical equipment,this paper proposes an automatic frequency control method of power supply of electrical equipment based on PI regulator.The innovation of this solution lies in the strong robustness of PI regulation,which can not only maintain the steady-state of the system,but also produce control effect in case of deviation to maintain the system steady-state.In this paper,an automatic and intelligent control framework is constructed.The results show that the proposed method can control the electrical stability of the independent power supply below ls,and achieve the electrical stability control of three-phase and single-phase AC side at 0.02s and 0.1ls,with high automatic and fast control ability.
