This report investigates the effect Flexible Alternating Current Transmission System (FACTS) devices have on the Singapore High Voltage Transmission System during a fault. Due to Singapore’s daily reliance on the electrical transmission system, ensuring that a fault does not compromise on the consistency and reliability of power is of vital importance. Power control devices are utilized to ensure that a fault can be mitigate so that it does not damage the grid infrastructure. One such class of power control devices are FACTS devices, which can control the reactive and active power flow in a system using power electronics devices, such as thyristors. This study investigates the effectiveness of FACTS devices as fault protection devices. Through extensive research, system modelling and using simulation software, this report’s objective is to present FACTS devices as a viable fault protection technique within Singapore’s transmission grid.
