Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] refer to Figure 1 to Figure 4 , the UPS configuration method of the offshore wind farm involved in this embodiment, first divides the UPS system of the offshore wind farm into three parts: the offshore wind turbine, the booster station and the centralized control center, and then divides the offshore wind turbine, the booster station and the centralized control center The center performs UPS system capacity selection, backup time selection, structural form and redundancy mode, UPS system DC input, equipment layout and UPS system wiring configuration;

[0035] 1) The UPS system capacity selection, the load capacity and characteristics of the UPS determine the capacity configuration of the UPS, and the UPS capacity is calculated according to the main loads of the UPS systems of the three parts respectively, and an appropriate margin is left;

[0036] 2) The sele...

Abstract

The invention discloses a method for configuring a UPS in an offshore wind plant. The method is characterized in that a UPS system is divided into three parts including an offshore wind power unit, a booster station and a centralized control center, wherein the booster station is divided into an offshore / island booster station and a land booster station according to the geographic position; according to the division, UPS system capacity selection, standby time selection, selection of a structural form and a redundancy method, UPS system direct current input, equipment arrangement and configuration of a UPS system wiring method are performed respectively; as for the configuration of UPS system standby time, fault possibility and corresponding fault repair time of offshore and land devices or systems are given full consideration, and a recommended value of standby time is given; and as for configuration of the UPS system redundancy method, the redundancy configuration methods suitable for being adopted by wind plants with different significances are given in the principle of the significance of the offshore wind plant in an electrical power system. The UPS system of the offshore wind plant is divided into three parts, reasonable configuration methods are selected according to different parts, and accordingly, the specific configuration methods are formed.

Description

technical field [0001] The invention relates to a UPS configuration method, in particular to a UPS configuration method for an offshore wind farm. It belongs to the technical field of electric equipment. Background technique [0002] With the development of electric power technology, new energy sources gradually replace traditional low-carbon energy sources, including wind energy, solar energy and ocean energy. Due to the characteristics of rich offshore wind resources and uniform wind speed distribution, offshore wind farms have huge room for development in countries or regions with rich coastline resources. With the rapid development of computer technology, computer monitoring is more and more widely used in the automation system of wind farms. In order to ensure the safe and stable operation of wind farms, computer monitoring and communication systems must be powered by UPS systems. However, offshore wind farms are far away from the shore and have long inspection and ma...
