【摘要】：控制非线性电子网络传输功率的稳定性,能够有效控制电源输出功率的均衡。传统方法将质量用效函数引入到非线性电子网络传输功率自动控制中,组建非线性电子网络功率自动控制模型,所需参数多,易出现指令错误,导致控制差的问题。提出基于同步电压源的非线性电子网络分布式功率自动控制方法。首先融合调频控制计算出各个电子逆变器输出频率和幅值的参考值,依据换流器基点运行功率得到其下垂控制系数,利用该系数促使各电子逆变器共同承担负荷功率波动,其次融合于模糊控制理论思想将联络线功率差作为模糊运算的输入量,输出一个对电子逆变器进行有功控制的PWM控制波形,以此为依据完成对非线性电子网络功率自动控制。仿真结果表明,所提方法控制精确度高,可以为非线性电子网络稳定运行提供科学的依据。
[Abstract]:Controlling the stability of the transmission power of nonlinear electronic network can effectively control the equalization of the output power of the power supply.The traditional method introduces the quality effect function into the transmission power automatic control of the nonlinear electronic network, and establishes the power automatic control model of the nonlinear electronic network, which requires a lot of parameters and is prone to the instruction error, which leads to the problem of poor control.A distributed power automatic control method for nonlinear electronic networks based on synchronous voltage source is proposed.Firstly, the reference value of output frequency and amplitude of each electronic inverter is calculated by fusing frequency modulation control, and the sag control coefficient is obtained according to the operating power of converter base point, and the load power fluctuation is caused to be shared by all electronic inverters.Secondly, combining with fuzzy control theory, the tie-line power difference is taken as the input of fuzzy operation, and a PWM control waveform for active power control of electronic inverter is outputted. Based on this, the power of nonlinear electronic network is automatically controlled.The simulation results show that the proposed method has high control accuracy and can provide a scientific basis for the stable operation of nonlinear electronic networks.
