Summary of the invention
In order to solve the problems referred to above of existing reactive power compensator, the utility model provides a kind of voltage-regulation type reactive power compensation filter.
Adopt the quick voltage regulator of carrying that has of novel quick oil immersed type on load tap changer, response speed is fast.Partly export the capacitive reactive power that lagging reactive power that lagging reactive power adds load is approximately equal to filter branch output by pressure regulation, make the reactive power at place, circuit collection point be approximately a constant little value, can in time compensate the vacancy reactive power and improve power grid quality, raising electrical network load capacity; By the effective filtering line harmonic of passive filtering group, the harmonic wave that load is produced is the least possible feeds back to higher level's electrical network.
The technical solution of the utility model is: from the bus place, with circuit breaker, isolating switch, current transformer, have and carry quick voltage regulator and be linked in sequence at end once, the pressure regulation motor drive mechanism has been connected to and has carried quick voltage regulator inside, voltage transformer and Controlled Reactor are connected in parallel to the secondary leading-out terminal that carries quick voltage regulator, form pressure regulation reactive power compensation unit; Be composed in series the passive filtering unit by filter reactor and filtering capacitor group, carry out filtering through the circuit breaker bus that inserts in parallel, and first-harmonic capacitive compensation capacity is provided.
