220kV风场变电站电气一次部分设计

Design of Electrical Primary Section of 220kV Wind Farm Substation

变电站是风电场电力系统中重要的组成部分,它的运行情况将直接影响着整个电力系统。本文主要对220 kV风场变电站进行了电气一次部分的设计。通过几种接线方式优缺点的对比确定出最优的电气主接线方案,选取短路点进行不同运行方式下的短路电流计算并根据其结果对主要电气设备进行选择及校验。

Substation is an important component of the wind farm power system,and its operation directly affects the entire power system.In this paper,the design of the electrical part of the 220kV wind farm transformer substation is carried out.By comparing the advantages and disadvantages of several connection modes determine the main electrical connection scheme optimization,short-circuit current selection points short-circuit under different operating modes of the calculation and selection and verification of the main electric equipment on the basis of the results.
