Abstract

One of the assessments for the reliability of the electric power system is the ability to serve the load needs continuously. There are no blackouts because there is an imbalance between the supply of electric power and the needs of the consumer load. The additional loads on the consumer side must be followed by the addition of power plants. Renewable energy is an alternative to increase the supply of electrical energy and does not damage the environment. However, the addition of new power plants can cause an increase in the contribution of short-circuit fault currents. The purpose of this paper is to compare the topology for the addition of renewable energy. The topology used is centralized and distributed generation. The renewable energy used consists of solar farm and wind farm. The best topology is a topology that produces lower short-circuit currents. Short circuit analysis methods used include the analysis of AC transient components, DC components, and AC rms components. Steady state short circuit simulation results show that distributed renewable energy contributes higher fault current than centralized renewable energy. Likewise, in the analysis of fault currents using the transient AC component, DC component, and AC component in rms value method, distributed renewable energy contributes higher fault current peak value than centralized renewable energy.
集中式和分布式可再生能源短路电流故障分量分析
对电力系统可靠性的评估之一是其持续满足负荷需求的能力。没有停电,因为电力供应和用电负荷之间是不平衡的。消费者方面的额外负荷必须伴随着发电厂的增加。可再生能源是增加电能供应的一种替代能源,而且不会破坏环境。然而,新电厂的增加会导致短路故障电流的贡献增加。本文的目的是比较可再生能源添加的拓扑结构。采用集中式和分布式的拓扑结构。使用的可再生能源包括太阳能发电场和风力发电场。最好的拓扑结构是产生较低短路电流的拓扑结构。短路分析方法包括分析交流暂态分量、直流分量和交流有效值分量。稳态短路仿真结果表明,分布式可再生能源比集中式可再生能源贡献更高的故障电流。同样,在暂态交流分量、直流分量和均方根法交流分量的故障电流分析中,分布式可再生能源比集中式可再生能源贡献的故障电流峰值更高。
