New-energy AC-DC integrated station power system used for transformer station

The utility model relates to a new-energy AC-DC integrated station power system used for a transformer station. The new-energy AC-DC integrated station power system includes a station AC bus connected with an output terminal of an in-station transformer, a station DC bus, a storage battery unit, a UPS power source and a communication power source bus. The new-energy AC-DC integrated station power system further includes a left photovoltaic array and a right photovoltaic array realizing output through a left disconnecting link and a right disconnecting link respectively. The lower port of the left disconnecting link and the lower port of the right disconnecting link are connected with each other through a DC circuit breaker. The left photovoltaic array is connected with the AC bus through the DC circuit breaker and a DC/AC module after outputting via the left DC disconnecting link. The right photovoltaic array is connected with the DC bus through the DC circuit breaker after outputting via the right DC disconnecting link. According to the utility model, a photovoltaic power generating system and an AC power system are combined with a DC power system effectively, such that station load matching can be realized flexibly and operation flexibility is improved substantially.
