Ideally, every substation has a busbar protection, but due to several reasons, often the busbar protection at a substation is not installed or installed but not active. The probability of disturbance on the busbar ranges from 6 - 8%, compared to interference in the High Voltage Air Line (SUTT), but the impact of disturbance caused by busbar interference if it is not properly protected by busbar protection will be very large and even have the potential to cause widespread blackouts or blackouts. Currently, the IEC 61850 GOOSE Massage protocol has become a requirement for the completeness of the protection relay, so that the protection relays can communicate well, even though they are of different brands. The presence of the IEC 61850 GOOSE Message protocol can be used as an alternative to support the implementation of a reliable, selective, inexpensive and easy to install busbar protection system, namely by coordinating the Z3 distance function with OCR coupling. improve the reliability of the Substation from busbar disturbances at the Bekasi 150 kV Substation. Compared to busbar protection with a current differential system, this busbar protection system based on the IEC61850 GOOSE Massage protocol has advantages such as operating flexibility, implementation time and installation costs} }
