Impact of integration of wind farms into a utility network on relay settings of the utility feeders

摘要: Generation of electricity using wind energy has received considerable attention worldwide in recent years. In order to generate significant amount electrical power a number based generators are usually grouped together form what is known as farm. Wind farms connected utilities' networks at distribution levels. Previous experience shown that the integration such plants into could make various impacts on host network. This includes safety well technical problems. Such problems include contribution fault currents, stability and reliability problems, introduction harmonics, voltage fluctuation, interference with process automatic control (AVC) networks, impact network losses etc. paper reports an investigation related determination settings protective devices feeders emanated from substation which farm connected. The study conducted simulated system consisting integrated Alternative Transient Program (ATP) also capability demonstrating dynamic behaviour during any disturbances may occur system. Results obtained several case studies will be presented discussed.
