摘要

风力发电厂(WPPs)必须在其连接点满足电网规范规定的无功功率要求。因此，所有WPP组件对无功能力的影响都很重要。WPP主变压器有载分接开关(OLTC)控制设置或控制方案可以在临界临界情况下进行优化，仅通过简单的控制设置调整即可实现足够的无功能力。研究了与WPP无功能力相关的OLTC控制电压参考参数值的影响，并指出在某些情况下，即使是相对较小的边际影响也会产生差异。此外，还介绍了一种确定OLTC电压控制参数最优值的方法，并在一个测试用例上进行了成功的验证。

Influence and optimal use of OLTC in wind power plants for reactive power capability requirement compliance

Wind power plants (WPPs) must fulfil Grid Code specified reactive power requirements at their connection points. Thus all the WPP components' influence on reactive power capability counts. The WPP main transformer On-Load Tap Changer (OLTC) control settings or control scheme can be optimized in critical borderline cases, possibly enabling sufficient reactive power capability just by a mere control setting adjustment. The influence of OLTC control voltage reference parameter values is studied related to WPP reactive power capability, and noted that even a relatively small marginal influence makes a difference under certain circumstances. In addition, a method for determining the optimal OLTC voltage control parameter values is introduced and demonstrated successfully on an example Test Case.
