Embodiment 1

[0021] The present invention is a typhoon-resistant control method for a wind power generating set. The wind generating set of the present invention is arranged in a wind farm in an area where a typhoon can affect the sea or coastal areas. The present invention specifically includes the following technical measures:

[0022] - Equip the central monitoring system (i.e. SCADA system, the same below) and generating units in the wind farm with emergency backup power supply. In order to reduce costs and ensure that the capacity of the emergency backup power supply is sufficient when doing work, the emergency backup power supply mode of the unit is equipped with multiple sets The unit is equipped with an emergency backup power supply, and the units corresponding to an emergency backup power supply are divided into multiple groups through the central monitoring system. The power supply time of each group of units is time-sharing according to the order of formation; of course, the emer...

Embodiment 2

[0038] The present invention is a typhoon-resistant control method for a wind power generating set. The wind generating set of the present invention is arranged in a wind farm in an area where a typhoon can affect the sea or coastal areas. The present invention specifically includes the following technical measures:

[0039] - Equip the central monitoring system (i.e. SCADA system, the same below) and the generating units in the wind farm with emergency backup power supply. The monitoring system divides the units in the wind farm into multiple groups, and the units in the same group are powered synchronously by their emergency backup power supplies. The power supply of the unit is time-sharing;

[0040] The emergency backup power supply of the above-mentioned units is at least used to provide emergency power supply for the yaw system, hydraulic station and main controller of the corresponding units;

[0041] The power supply status of the emergency backup power supply of the ...

Abstract

The invention discloses an anti-typhoon control method for a wind generating set. The method comprises the following technical measures: equipping standby emergency power supplies for a central monitoring system and a set, wherein the standby emergency power supply of the set is at least used for providing emergency power supply for a yaw system, a hydraulic pressure station and a master controller of the set; interlocking a power supply state of the central monitoring system and the set and a power supply state of a power grid to the central monitoring system and the set by the standby emergency power supply, so that the power supply states of the standby emergency power supply and the power grid are automatically switched; setting an operating state of the set through the central monitoring system, wherein when the set is positioned in a typhoon environment, the set performs a yaw maneuver, and a main shaft hydraulic brake on the set is positioned in a release state, so that the setis positioned in an automatic yaw state; and performing manual inspection on the set after the typhoon, performing self-inspection on the set by the central monitoring system after qualified, and enabling the unit to be positioned in a normal operating mode in the self-inspection process.

Description

technical field [0001] The invention relates to a control method of a wind power generating set, in particular to a control method of a wind power generating set in an area that can be affected by a typhoon, more specifically, a control method of a wind power generating set against a typhoon. Background technique [0002] my country is located in the east of the Asian continent, bordering the Pacific Ocean, and is located in the southeast monsoon belt. It has about 32,000 kilometers of coastline (including about 18,000 kilometers of mainland coastline and about 14,000 kilometers of island coastline), and the island area is about 75,400 km 2 , with an area of ​​about 12,700 km near the beach 2 , the southeast coast, Shandong Peninsula, Liaodong Peninsula and offshore islands are the largest wind energy resource areas in my country, and the wind energy resources are quite rich. In addition, my country's southeast coastal areas have a relatively developed economy, consume a lo...
