Distributed Generators (DGs) provide a number of advantages for utilities. So, they become very common these days. However, DGs can also negatively impact some aspects of distribution system such as Overcurrent (O.C.) protection. DGs are known to contribute fault currents to their interconnected power system. As a result, there is a concern that the DGs may affect the coordination of O.C. protection...
With recent proliferation of wind farms over the world, it has become important to study the short circuit characteristics of different types of wind turbine generators (WTGs). This paper describes the short circuit characteristics of a Type-II WTG, and a wind farm comprised of this type of generators. A commercial time-domain software is used to model the WTG and the wind farm. The machine model...
Demand for wind power has been tremendously increasing, as a result of which large Wind Power Plants (WPPs) with hundreds of generating units are being installed producing substantial power. Therefore, it has now become important to analyze the short circuit behavior of Wind Turbine Generators (WTGs) when connected to the utility grid. The short circuit behavior depends not only on the type of WTGs...
An important aspect of wind power plant (WPP) impact studies is to evaluate short-circuit current (SCC) contribution of the plant into the transmission network under different fault conditions. This information is needed to size the circuit breakers, to establish the proper system protection, and to choose the transient suppressor in the circuits within the WPP. This task can be challenging to protection...
