| Summary: | The understanding of the transient stability on power systems is very important to power engineer. Theoretically, there were two types of stability in power systems which are steady-state stability and transient stability. Since transient stability gives a big impact to power systems operation, so, the study on the transient stability is conducted. There were many FACTS devices that can be used to improve the transient stability on the power system network, such as UPFC, SVC, DVR, HVDC-Light and so on. HVDCLight was an idea to connect the power network from Bakun to peninsular Malaysia through the submarine cable. HVDC-Light has been chosen to be analyzed since this technology has not been completed. So, the simulation for this system has been designed in PSCAD software. HVDC-Light comprises two Voltage Source Converters (VSCs), one operating as rectifier and the other operating as inverter. The simulation of this project involves the two buses system, synchronous machine and generator. So, the circuit without the HVDC-Light and the circuit with HVDC-Light are designed in the PSCAD software. Then, the comparison of the output which is consists of active power, reactive power, voltage and internal phase angle for the synchronous machine between those two circuits will be made. The result shows that HVDC-Light improved the transient stability and power generation on the power systems network |
