Black start coordination device and method for a wind farm

Abstract

The invention provides a black-start coordination apparatus and method of a wind power plant. The apparatus comprises an EMS, an SCADA system and a wind power plant black-start coordination system. The steps for a black start by use of the apparatus comprise: when a power system generates a fault and fails, a wind power plant black-start coordination system, through real-time monitoring data of each blower fan branch, sent by the EMS and energy storage apparatus load information monitored by an SCADA module, determines whether a condition for the back start by use of a blower fan is satisfied; and under the condition that the back start is performed by use of the blower fan, data in the whole wind power plant is searched through the EMS and the SCADA system, a whole black-start process is controlled through interaction among the wind power plant black-start coordination system, the EMS and the SCADA system, and thus the whole black-start process is completed. By use of the technical scheme provided by the invention, the success rate of the black start of the wind power plant can be improved.

Description

technical field [0001] The invention relates to the field of electric field black start, in particular to a black start coordination device and method for a wind farm. Background technique [0002] Black start means that after the entire power grid system collapses and loses power, it can be self-started through the internal power station without relying on external systems. After startup, the isolated power stations are interconnected with each other to re-establish a normal power network system. [0003] Generally speaking, traditional black start power sources include hydropower stations and thermal power stations. However, with the aggravation of energy crisis and environmental problems, black start using new energy is a forward-looking and strategic plan. [0004] The traditional scheme of using hydropower station and thermal power station for electric field black start has the following limitations: the scheme of using hydropower station for black start is easily affe...

Problems solved by technology

However, with the intensification of energy crisis and environmental problems, using new energy for black start is a forward-looking and strategic plan

[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

[0005] The existing black start methods of wind farms largely rely on the spontaneous operation of each branch system during the whole start-up process, and the coordination between each branch system is low, so the success rate of black start is also low
