摘　　要：为提高变电站调度和自适应控制能力,提出基于电网等效惯量特征分析的变电站调度中心单线图模数图一致性测试优化方法。分析变电站调度中心单线图的电力控制参数,通过系统辨识模型参数识别法,融合变电站调度中心单线图模特征分解和信息,分析单线图模数图一致性的离散估计值。以等值机组惯量以及负荷为测试参数,设计单线图模数图一致性测试的控制律。通过功率增量分析法,控制变电站调度中心单线图模的等效电路优化设计和动态响应,实现单线图模数图一致性测试模型优化设计。实验结果表明,所设计的变电站调度中心单线图模数图一致性测试优化方法的精度较高、自适应控制能力较好,有利于变电站的统一调度,具有很好的大扰动抑制能力。In order to improve the substation dispatching and the adaptive control ability,an optimization method for consistency test of substation dispatching center single line diagram modulus diagram based on the analysis of equivalent inertia characteristics was proposed.The power control parameters of the substation dispatching center single line diagram were analyzed.By using the parameter identification method of system identification model,combining the model decomposition and the information of substation dispatching center single line diagram,the discrete estimated value of the consistency of the substation dispatching centeringle line diagram was analyzed.Taking the inertia and load of equivalent units as test parameters,the control law for consistency test of the single line graph modulus graph was designed.Through the power increment analysis method,the equivalent circuit optimization design and dynamic response of the substation dispatching center single line diagram model were controlled,and the consistency test model of the single line diagram module diagram was optimized.The experimental results show that the optimization method has high precision and good adaptive control ability,which is beneficial to the unified dispatching of substations and has good capability of suppressing large disturbance.
