Abstract

A wind power plant consists of a large number of turbines interconnected by underground cable. A pad-mount transformer at each turbine steps up the voltage from generating voltage (690 V) to a medium voltage (34.5 kV). All turbines in the plant are connected to the substation transformer where the voltage is stepped up to the transmission level. An important aspect of wind power plant (WPP) impact studies is to evaluate the short-circuit (SC) current contribution of the plant into the transmission network under different fault conditions. This task can be challenging to protection engineers due to the topology differences between different types of wind turbine generators (WTGs) and the conventional generating units. This paper investigates the short circuit behavior of a wind power plant for different types of faults. The impact of wind turbine types, the transformer configuration, and the reactive compensation capacitor will be investigated. The voltage response at different buses will be observed. Finally, the SC line currents will be presented along with its symmetrical components

影响风电场短路行为的不同因素

风力发电厂由大量的涡轮机组成，通过地下电缆相互连接。每个涡轮机上的垫式变压器将电压从发电电压(690 V)提升到中压(34.5 kV)。工厂中的所有涡轮机都连接到变电站变压器，在那里电压上升到传输电平。风电场影响研究的一个重要方面是评估风电场在不同故障条件下对输电网的短路电流贡献。由于不同类型的风力发电机(wtg)和传统发电机组之间的拓扑结构差异，这项任务对保护工程师来说是具有挑战性的。本文研究了风电场在不同故障类型下的短路行为。将研究风力涡轮机类型、变压器配置和无功补偿电容器的影响。将观察不同母线的电压响应。最后，SC线电流将与其对称分量一起呈现
