Embodiment 1

[0037] Such as figure 1 as shown,

[0038] A linkage method for an auxiliary control system of an offshore wind farm, comprising the following steps:

[0039] S1. Establish the data model of the auxiliary control equipment in each auxiliary control subsystem of the offshore wind farm, and obtain the linkage relationship between the auxiliary control equipment, as shown in Table 1.

[0040] Table 1

[0041]

[0042]

[0043] It can be seen from Table 1 that the auxiliary control subsystems include maritime personnel tracking and positioning system, ship online monitoring system, hydrology and sea state monitoring system, submarine cable online monitoring system, HVAC system, fire alarm system, access control system, public broadcasting system, main On-line oil chromatography monitoring system, SF6 monitoring system and video monitoring system;

[0044] The auxiliary control equipment of the maritime personnel tracking and positioning system is the marine personnel alar...

Embodiment 2

[0062] Implementation is carried out according to the steps of an auxiliary control system linkage method for offshore wind farms in Embodiment 1, wherein the data model in step S1 may include multiple sea personnel, and one sea personnel includes the following attributes: basic personnel information, start time of going to sea, End time, real-time latitude and longitude information; the corresponding linkage relationship also includes a public broadcasting system;

[0063] The data model can contain multiple ship information. A ship contains the following attributes: crew information, real-time latitude and longitude information; it also includes a public address system for alarm linkage; the corresponding linkage relationship also includes a public broadcasting system;

[0064] The data model can contain one or more micro-weather stations. A micro-weather station contains the following attributes: instantaneous wind speed, average wind speed, wind direction, temperature, rel...

Abstract

The invention discloses an offshore wind farm auxiliary control system linkage method, comprising the steps of establishing a data model of an auxiliary control device in each auxiliary control subsystem of an offshore wind farm, and acquiring a linkage relationship between the auxiliary control devices; defining, according to the linkage relationship, a linkage alarm type, a linkage alarm mode, alinkage alarm behavior and a linkage alarm operation; acquiring a real-time alarm signal; obtaining a specific linkage operation; performing the linkage operation and verifying the result of the linkage operation. The offshore wind farm auxiliary control system linkage method achieves an interactive communication function of the offshore wind farm auxiliary control system, can conveniently locateaccidents, understand the accident situations in real time, and take effective measures in time to prevent accidents from expanding.

Description

technical field [0001] The invention belongs to the technical field of green energy power generation, and in particular relates to a linkage method for an auxiliary control system of an offshore wind farm. Background technique [0002] my country has abundant reserves of offshore wind energy resources available for development, and the offshore wind power industry is developing rapidly. Compared with onshore wind power, offshore wind power has 20% to 40% higher energy efficiency of wind energy resources, and has the advantages of large unit capacity, high wind speed, high effective wind energy density, long utilization hours, and large power generation. [0003] However, the environment of offshore wind farms is harsher than that of land wind farms, requiring more monitoring objects and more subsystems and intelligent electronic devices. Since each subsystem is independent of each other and data cannot be shared, a large number of monitoring backgrounds exist in a wind farm...
