Summary: | Parallel induction generator with a synchronous generator is one of the solution to meet the demand for electricity in isolated area that lack electricity network as providers of reactive power. Synchronous generator is not always able to meet the reactive power requirements, so we need other sources of reactive power. Reactive power compensator such as Static VAR Compensator Magnetic Energy Recovery Switch (SVC�MERS) is able to work dynamically following the load change given to the system. The principle works set the charging time of the capacitor charge and discharge by controlling the ignition angle (δ) so as to compensate for reactive power and inject capacitive currents.
This study uses PSIM 9.0.3.400 software that aims to identify the characteristics of the parallel SVC�MERS induction generator with synchronous generator. Simulation results show when the parallel induction generator with synchronous generator, induction generators absorb reactive power of synchronous generator. The system was tested with full load resistive - inductive synchronous generator with power factor 0.85, it turns the synchronous generator power factor is at a point 0.71 which causes increased 1,005 p.u active power and 1.19 p.u apparent power. This is due to the induction generators become inductive loads for synchronous generator. When parallel SVC�MERS induction generators with a synchronous generator, the system can be tested with a resistive - inductive load smaller to gain greater power because there is a new reactive power providers. When the rotor speed of the induction generator 1 and induction generator 2 at 1507.8339 RPM, turns the induction generator 1, induction generator 2 and synchronous generator power factor is at the point 0.85. When the rotor speed of the induction generator 1 is different from induction generator 2, reactive power provider SVC�MERS tend to provide reactive power equal to the induction generators. As a result, the low-speed induction generator absorb reactive power will be excessive so that the active power decreases but increases the apparent power and power factor is poor.
