| 摘 要： | 采用MATLAB2008A和TMS320F28335高速浮点DSP为核心器件半实物仿真装置,对特高压输电系统进行了建模仿真和实时控制的研究。控制系统采用RBF神经网络整定PID算法,动态跟踪特高压交流输电线路的过电压,快速实现系统的闭环控制。仿真试验表明,基于RBF神经网络整定PID控制的特高压磁阀可控电抗器,能动态抑制电网工频暂态过电压,在该控制模式下,单段输电线路的等效长度可以进一步延长,提高特高压交流线路的输电能力和经济性。

| Abstract: | MATLAB2008A and high speed floating point DSP,TMS320F28335,are used as core devices to form semi-physical simulator to perform simulation and real-time control of UHV transmission system.PID control algorithm based on RBF neural network is used to dynamically track UHV AC transmission system overvoltage and realize closed-loop system control.Simulated tests show that the UHV MCR with PID control based on RBF neural networks is capable of dynamically suppress grid transient overvoltage at working frequency,a... |
