Protection coordination analysis applied at biogas power generation plant

Biogas from liquid waste palm oil processing, mill effluent (POME), can be utilized in biogas power plants as a source of renewable energy (PLTBg). The PLTBg electrical system is equipped with coordinated protection system. Then, the must also maintain continuity service parts that are not affected by disturbances. Coordination essential. In this research, transient analysis program (ETAP) carries out short circuit current analysis, and coordination overcurrent constructed its inverse-definite minimum time characteristics. analyzed data contributed to selecting right devices. A combination protection, directional frequency change rate supported reliable for generation plant distributed generation. result shows modern microprocessor-based relays support several features one device integrated into supervisory control acquisition (SCADA)-controlled enhance their capabilities.
