Abstract

Based on an electrical power system, protection is the most important thing for a power system to protect users and equipment from harmful things. It can also detect abnormal situations, such as an overcurrent in the power system.Then, the benefits of protection can also prevent equipment from being damaged and avoid short circuit breakers. Generally, overcurrent occurs when a short circuit happens in the power system. These are caused by injury to a cable or disturbance in the environment. As a result, the current flowing through the system has increased dramatically. Aside from that, earth faults can occur between phases of the ground.There are different types of faults, such as single phase on the ground, two phase on the ground, and three phase on the ground.The goal of this project is to identify the capabilities of a relay on the various types of power system faults.Also, PSCAD software was used to determine whether the circuit assembly was installed correctly and the same thing happened with the drawing. In this project, the drawings from electrical distribution at the TNB Manjung thermal power plant were obtained to determine more effectively by using PSCAD software.
