Wind turbine generator set black start capability verification system and method

Abstract

The invention discloses a wind turbine generator set black start capability verification system and method. The system comprises an external power supply G1, a wind turbine generator set, an SVG system, a simulation load L1, a matching load L2, a box type transformer T1, a box type transformer T2, a load transformer T3 and an engine room transformer T5. The external power supply G1 is connected with the wind turbine generator set. The wind turbine generator set is connected with the box type transformer T1. The box type transformer T1 is connected with a bus F1. The SVG system is connected with the bus F1. The simulation load L1 is connected with the load transformer T3. The matching load L2 is connected with the engine room transformer T5. The load transformer T3 and the engine room transformer T5 are connected with the box type transformer T2. The box type transformer T2 is connected with the bus F1. The matching load L2 is connected with an energy management system. The wind turbine generator set is connected with the energy management system through a wind turbine generator monitoring system. The real black start is simulated so as to verify the black start capability of the wind turbine generator set.

Description

technical field [0001] The invention relates to the field of electric field black start, in particular to a system and method for verifying the black start capability of a wind turbine. Background technique [0002] Black start means that after the entire power grid is out of service due to external or internal faults and enters a completely black state, it does not rely on the help of the external power grid, only by starting the power supply with black start capability inside the power grid, and then driving to restore the power supply without black start capability in the power grid. Gradually expand the recovery scope of the system, and eventually achieve the restart of the entire grid. [0003] For the black start problem of the power system, traditional black start power sources include hydropower stations and thermal power stations. However, with the aggravation of energy crisis and environmental problems and the widespread use of new energy, it is a strategic plan t...

Problems solved by technology

[0004] The traditional scheme of using hydropower stations and thermal power stations for electric field black start has the following limitations: the scheme of using hydropower stations for black start is easily affected by seasonality, and during the dry season in winter, there is often not enough water to support the black start of hydropower stations
