Embodiment Construction
[0021] The present invention will be further described below in conjunction with accompanying drawing:
[0022] Such as figure 1 As shown, the oil field pumping unit distributed grid-connected wind power complementary power supply system of the present invention includes a wind power generator set (1), a converter device (2), an electric energy metering device (3), a step-up transformer (4), a wind power It consists of a power generation control and protection system (5), a step-down transformer (6), and a pumping unit (7).
[0023] The sources of electric energy include the system grid power supply S1 and the wind turbine power supply S2, which jointly supply power to the pumping unit power distribution line. Among them, the system grid power supply S1 is generally a substation, and the wind turbine power supply S2 is composed of the wind turbine (1) through the converter device (2), the electric energy metering device (3), and the step-up transformer (4). Grid power S1 is ...
