A Analisis Setting Speed Droop dan Deadband Governor Unit 1 PLTA Maninjau Sebagai Pengaturan Frekuensi pada Sistem 150 KV

Maintaining the stability of active power and frequency between generator network system is very important, because if output are unstable, it will cause damage to generator. influenced by speed drop deadband settings. Speed ​​droop a percentage number that states sensitivity generating unit in responding changes, while change value at which governor begins respond increase or decrease generator's output. The smaller droop setting, more sensitive changes working range geovernor also getting smaller. Inaccuracies setting can affect work unit. purpose this study was analyze effect 1 PLTA Maninjau. This uses quantitative methods with descriptive analysis techniques. data source used operational Maninjau 1. be analyzed based on determination values ​​that Based sources obtained from hydropower, settings 8% 4% for droop, 0.6% 0.2%, respectively. rules, difference allowed 1% 0.5 Hz when viewed 1, there no greater than Hz. From calculation (governor response) seen therefore set setting. Keywords: Load, ​​droop, Deadband , Frequency
