【摘要】:文章提出了一種基于同步相量測量(PMU)數(shù)據(jù)并用于估算配電網(wǎng)負載模型的和聲搜索算法(HSA)改進分布式測量。由于近年來分布式發(fā)電的發(fā)展,燃料電池和風力渦輪機等的接入使得配電網(wǎng)的拓撲結構進一步復雜。因此,需要通過改變傳統(tǒng)的分布荷載模型來克服這個問題。估算模型不僅要在網(wǎng)絡正常條件下和真實模型作出相同的反應,而且在網(wǎng)絡故障和瞬態(tài)條件下是有效的。本中,負荷模型及其相應的方程已被修改。雙反饋感應電機(DFIM)的參數(shù)估算以及在網(wǎng)絡頻率變化情況下負載電源的可靠性都包含在模型中。該模型在Matlab/Simulink環(huán)境下進行仿真驗證該算法的有效性。
[Abstract]:In this paper, a harmonic search algorithm based on synchronous phasor (PMU) data and used to estimate the load model of distribution network is proposed. (HSA) is used to improve the distributed measurement. Due to the development of distributed generation in recent years, the connection of fuel cell and wind turbine makes the topology of distribution network more complicated. Therefore, it is necessary to overcome this problem by changing the traditional distributed load model. The estimation model should not only react the same as the real model under the normal condition of the network, but also be effective under the fault and transient conditions of the network. In this paper, the load model and its corresponding equations have been modified. The estimation of (DFIM) parameters and the reliability of load power supply in the case of network frequency change are all included in the model. The model is simulated in Matlab/Simulink environment to verify the effectiveness of the algorithm.
