Abstract

Renewable energy has become a new trend in power systems. Renewable-based power plants such as wind power systems and photovoltaics. This paper proposed a novel method for inertia emulation based on superconducting magnetic energy storage (SMES). To get better inertia support for the system, a type-2 fuzzy controller is used as the SMES controller. An area power system is used as the test system to investigate the performance of type-2 fuzzy controller on SMES. Time domain simulation is carried out to show the efficacy of the proposed method. From the simulation results, it is found that the proposed controller can reduce the overshoot of frequency by up to 20% compared to the type-1 fuzzy controller. It is also hoped that the proposed method can be used as a reference of the Industrial people.

Abstract

With the increasing demand for electricity in Indonesia, both industrial and household, a reliable electrical system is required. One of the electrical system faults, such as a short-circuit fault in a generator, can disrupt electricity delivery and cause damage to equipment. This research concentrates on analyzing short circuit faults in the Ambon Peaker Gas Oil Power Plant (PLTMG), which has four generator units with a capacity of 30 MW. The main objective of this study is to determine how much short-circuit fault current occurs during three-phase, phase-phase, and phase-ground faults, as well as the components that affect these currents. Data collection on power system characteristics and the use of ETAP (Electrical Transient Analysis Program) software were used. The results showed that there was a short-circuit current fault at bus 1 of the Ambon MHP with a three-phase fault of 14.727 kA, a ground-phase fault of 15.998 kA, and a phase-phase fault of 12.926 kA. With these results, this study provides recommendations for the selection of appropriate protection equipment to minimize losses due to disturbances in the power system at the Ambon Peaker MHP.   Keyword : Short circuit fault, PLTMG, ETAP
