Protection relay functions: over voltage, current, phase 3. Jadi jika sebelumnya primemover menggerakkan generator, maka pada kondisi ini primemover digerakkan oleh generator yang berperan sebagai motor. It really depends on what it says in the data sheet! Under normal power flow, the trip contact on the disc are open and rotation is restricted by stoppers but if a reverse power starts to flow the disc is rotated in opposite direction, moves away from the stoppers in the direction of trip contact that activates the trip. Reverse reactive power protection for small generators The reverse power relay consist of light weight non-magnetic aluminium disc, mounted on a spindle which has slow friction bearings, is positioned in a gap between two electromagnets. It quickly activates the trip if the output falls below a preset value and disconnects the generator to avoid any damage. One way of testing the reverse power relay, is to reverse the polarity of the PT voltage to the relay, block the trip, and increase the KW of the turbine to the tripping point and see that it works. How do you reset reverse power? - Heimduo Necessary cookies are absolutely essential for the website to function properly. As the power relay senses the reverse power flowing into The generator, it opens the main circuit breaker of no.1 generator. Reverse power relay basics and operation - Electrical Equipment Kode ANSI yang terdapat pada suatu alat proteksi menentukan gangguan apa saja yang dapat dimonitor sehingga melakukan tindakan proteksi pada sistem kelistrikan dan komponennya dari kerusakan saat terjadi kejadian yang tidak diinginkan.

R, Sesuai dengan namanya, relay ini ketika aktif akan mengunci seluruh rangkaian instalasi. The action you just performed triggered the security solution. The reverse power element is used to protect the generator against motoring, which can be hard on mechanical equipment and unnecessarily draws power from the grid. that means mechanical power gets converted to electrical power and this power is given to the grid. Reverse power relays are directional relays used to protect the generators. You can use a reverse current relay with a DC generator & that's what they use. Distributed Generator Interconnection Relay. 0000034301 00000 n There are some mechanical linkages provided in the circuit which instantaneously operates the circuit for preferential trips. Baslier Electric is another manfacturer of 32 ( reverse power ) relays. A generator can work as a synchronous compensator if the driving torque is less than the total losses in the system, taking necessary power from the network. The 51V relay characteristics are plotted on a phase TCC along with the generator decrement and overload curves, and the feeder damage curve. www.electrotechnical-officer.com uses cookies to improve your experience.
