中文摘要:

本文提出了一种基于PMU测量数据并用于估算配电网负载模型的和声搜索(Harmony Search)改进分布式测量。由于近年来分布式发电的发展,燃料电池和风力涡轮机等的接入使得配电网的拓扑结构进一步复杂。因此,需要通过改变传统的分布荷载模型来克服这个问题。估算模型不仅要在网络正常条件下和真实模型作出相同的反应,而且在网络故障和瞬态条件下是有效的。在本文中,负荷模型及其相应的方程已被修改。双反馈感应电机(DFIM)的参数估算以及在网络频率变化情况下负载电源的可靠性都包含在模型中。该模型在Matlab/Simulink环境下进行仿真验证该算法的有效性。

英文摘要:

In this paper a new technique for estimation of distribution network load model parameters based on PMU measurements data and Harmony Search Algorithm (HSA) is proposed. Distribution network loads reveal some complicated behavior as these networks are connected to distributed generations(DG) such as fuel cells or wind turbines which implements modern electrical machines. Therefore, the conventional models of the distribution loads should be modified to overcome this problem. In this paper the load model and its relative equations has been modified. Estimation of the double fed induction machine(DFIM) parameters and load power-dependability to network frequency change are included in the model. The proposed model is simulated in Matlab/Simulink software under some normal and abnormal conditions of the network.
