【摘要】：为解决高压直流控制系统参数优化问题,提出一种基于PSCAD-MATLAB联合调用的参数优化方法。阐述了联合调用的可能性和基本原理,介绍了联合调用实现优化的基本流程。以CIGRE标准测试系统为研究模型,采用改进粒子群优化算法优化整流侧定电流控制中PI控制器参数。经过比对原参数、基于传递函数优化方法的结果及基于基本粒子群算法的联合调用优化结果表明,联合调用策略准确复现了直流系统实际工作性能,依靠改进粒子群算法的全局搜索能力,有效实现了直流输电控制系统的参数优化,提升了直流输电系统的瞬态和稳态性能。联合调用优化控制参数方法的提出为直流输电控制系统的各个参数的整定和优化提供了重要的参考决策。
[Abstract]:In order to solve the parameter optimization problem of HVDC control system, a parameter optimization method based on joint call of PSCAD-MATLAB is proposed. This paper expounds the possibility and basic principle of joint call, and introduces the basic flow of realizing optimization of joint call. Using CIGRE standard test system as the research model, the parameters of Pi controller in rectifier side constant current control are optimized by improved particle swarm optimization (PSO) algorithm. After comparing the original parameters, the results based on the transfer function optimization method and the joint call optimization based on the basic particle swarm optimization algorithm show that the joint call strategy accurately reproduces the actual working performance of the DC system. Based on the improved particle swarm optimization (PSO) algorithm, the parameter optimization of HVDC control system is realized effectively, and the transient and steady performance of HVDC system is improved. The joint call of optimal control parameters provides an important reference decision for the tuning and optimization of each parameter of HVDC control system.
