Abstract

In the sending-end power grid of HVDC with large-scale wind power integration, aiming at the problem of wind turbine generators tripping caused by transient over-voltage after DC faults, a synchronous condenser (SC) optimal configuration method in the sending-end grid is proposed, which takes into account the control effect and configuration cost. Based on the analysis of the mechanism of wind turbine generators tripping caused by DC faults and the influence of SC on wind turbine generators tripping, firstly, a SC layout model based on the improved reactive-voltage sensitivity is established to determine the installation location of the SC. Secondly, wind turbine generator tripping security margin (WTSM) and the SC configuration cost are introduced to establish the multi-objective optimization model and determine the SC installed capacity. Finally, the feasibility and effectiveness of the configuration method are verified by an actual HVDC and its near-field wind farms.

一种基于抑制风电机组在高压直流发送端电网跳闸的同步冷凝器配置方法

在大型风力发电一体化的高压直流输电发送端电网中，针对直流故障后瞬时过电压引起的风力发电机组跳闸问题，提出了一种兼顾控制效果和配置成本的发送端电网同步冷凝器(SC)优化配置方法。在分析了直流故障导致风电机组跳闸的机理以及电网对风电机组跳闸影响的基础上，首先建立了基于改进无功电压灵敏度的电网布局模型，确定了电网的安装位置;引入风电机组脱扣安全裕度和机组配置成本，建立多目标优化模型，确定机组装机容量。最后，通过实际直流输电及其近场风电场验证了该配置方法的可行性和有效性。
