Abstract

The offshore wind farm is close to the load center, and its development scale is getting larger and larger. In order to study the dynamic characteristics of wind farms, it is obviously impractical to take detailed wind farm model as research object. In this paper, on the principle of keeping the external characteristics of the wind farm unchanged, an aggregation study of the wind farm taking into account the submarine cable capacitance effect is given. In addition, the aggregation method of the internal parameters of the wind turbine generators (WTGs) and the collector system are given. Finally, a detailed wind farm model with 34 squirrel-cage induction generator (SCIG) WTGs and the corresponding aggregated model are established on PSCAD simulation software. The dynamic characteristics of the two models at the point of common coupling (PCC) under grid fault condition are simulated and compared. The results show that the proposed dynamic aggregation method can present the dynamic characteristics of wind farm with high accuracy, and can be popularized for other types of wind farm.

海底电缆电容对基于scig的风电场动态聚集建模的影响

海上风电场离负荷中心较近，开发规模越来越大。为了研究风电场的动态特性，以详细的风电场模型作为研究对象显然是不现实的。本文在保持风电场外部特性不变的原则下，对考虑海底电缆电容效应的风电场进行了集合研究。此外，还给出了风力发电机组和集热器系统内部参数的聚合方法。最后，在PSCAD仿真软件上建立了34台鼠笼式感应发电机(SCIG) wtg的详细风电场模型和相应的聚合模型。仿真比较了两种模型在电网故障情况下共耦合点的动态特性。结果表明，所提出的动态聚合方法能较准确地反映风电场的动态特性，可推广应用于其他类型的风电场。
