SISTEM TENAGA LISTRIK
1.Sistem Pembangkitan (Generation)2.Sistem Penyaluran (Transmission)
– Penghantar (transmission line)– Gardu Induk (substation)– Pusat Pengatur (Control Centre)
3.Sistem Distribusi (Distribution)
GARDU INDUK
Fungsi GI :– Mentransformasikan daya listrik– Untuk pengaturan pelayanan beban ke GI lain,
dan ke Gardu distribusi– Untuk pengamanan sistem tenaga listrik– Untuk pengawasan operasi (pemantauan,
pengukuran dll)
JENIS-JENIS GI
• Berdasarka tegangannya• Berdasarkan fungsinya• Berdasarkan Isolasi• Berdasarkan sistem rel (Bus bar)
PERALATAN GI
1. Primary Equipment (High Voltage)2. Secondary Equipment (Low Voltage)
PERALATAN GIPrimary Equipment (High Voltage)
– Busbar– Lines– Transformer (Power Transformer, Instrument
Transformer– Kapasitor– Shunt Reactor– Motor– Circuti Breaker– Disconneting Switch– Earthing Switch– Lightning Arrester
PERALATAN GISecondary Equipment (Low Voltage)
– Protection (Distance Relay, Differencial Relay, Eart Fault Relay, Over Current Relay, dll)
– RTU for Monitoring, Control, and measuring– Transducer for measurement (I, kV, MW, MVar, f)– Logger/Recording (event logger, DFR, data logger,
EWS, TWS)– Telecommunication (PLC, Multiplex, PABX)

TREND PERKEMBANGAN GI• GI Konvensional
– Local operation– Manual collection, evaluation, dan forwarding data
to higher level system– Distributed system
• GI Semi Otomasi – Remote Operation from Control Centre (SCADA)– Centralized System– Automatic data collection, evaluation and
forwarding• GI Otomasi (Substation Automation) ???

IMPLEMENTASI GI OTOMASIContoh Implementasi
IMPLEMENTASI GI OTOMASIContoh Implementasi
BENEFIT GI OTOMASI– Less Hardware (panel and cubikle)– Less cabling (hard wire)– Less installation– Less space demand and civil work– Less maintenance (CBM)– One point of data collection (information,
evaluation, analisis)– Economic, effective, and Save Operation and
maintenance– Easy extensions and function implementation
BENEFIT GI OTOMASI– Improve availability due to self-supervision and
redundancy– Reduced cost :
• Installation, commissioning, operation, maintenance, and life-cycle
– No conventional mimic board/panel control– Optical link Reduced EMC – On-line primary equipment monitoring– Open system
