Embodiment 1

[0090] Embodiment 1 provides a calculation method for the maintenance cost of an offshore wind farm. The maintenance cost includes wind power loss cost, transportation cost, resource cost and labor cost. In this embodiment, the maintenance cost is the wind power The sum of the loss cost, the transportation cost, the resource cost and the labor cost, but not specifically limited to the maintenance cost, it can also be the sum of any combination of the four costs, and the calculation method includes wind power loss cost The calculation steps of , the calculation steps of transportation costs, the calculation steps of resource costs and the calculation steps of labor costs.

[0091] Specifically, such as figure 1 As shown, the calculation steps of the wind power loss cost include the following steps:

[0092] Step 1101: Generate a standard power generation model of the wind turbine according to the design wind speed and power curve of the wind turbine.

[0093] In this step, th...

Embodiment 2

[0123] Such as Figure 5 As shown, embodiment 2 provides a maintenance scheduling method for an offshore wind farm, and the maintenance scheduling method includes the following steps:

[0124] Step 201. Obtain n maintenance tasks for different wind turbines, m ships and x maintenance personnel for performing maintenance tasks.

[0125] In this step, the specific information of the maintenance tasks to be performed is obtained from the SCADA data of the offshore wind farm, such as the geographical distribution of the wind turbines and wharves, the damage type of the wind turbines, etc., and then the maintenance personnel who can currently perform maintenance tasks are obtained. Quantity and skills, the number of ships that can be dispatched at present, etc., in this embodiment, set m<x<n, but the relationship is not specifically limited.

[0126] Step 202: Randomly encode the execution order of n maintenance tasks, and generate n! Group task sequence.

[0127] In this step, ...

Embodiment 3

[0164] Such as Figure 7 As shown, Embodiment 3 provides a calculation system 1 for maintenance costs of offshore wind farms, including a processing module 11 and an output module 12, and the processing module 11 includes a wind power loss cost calculation unit 111, a traffic cost calculation unit 112, and a resource cost calculation unit. Unit 113 and labor cost calculation unit 114, the maintenance cost includes wind power loss cost, traffic cost, resource cost and labor cost, in this embodiment, the maintenance cost is the wind power loss cost, the traffic cost , the sum of the resource cost and the labor cost, but does not specifically limit the maintenance cost, and may also be the sum of any combination of the four costs.

[0165] Specifically, the processing module is used to generate a standard power generation model of the wind turbine according to the design wind speed power curve of the wind turbine. The processing module obtains the design wind speed and power cur...

Abstract

The invention discloses a maintenance cost calculation and maintenance scheduling method and a system for an offshore wind farm. The calculation method comprises a step of wind power loss cost calculation. The step of wind power loss cost calculation comprises sub steps: according to a designed wind speed power curve of a fan, a standard generation model of the fan is generated; wind speed prediction data in a preset time period are acquired; according to the wind speed prediction data and the standard generation model, the standard total generation amount of the to-be-maintained fan in the preset time period is calculated; the fan maintenance time period in the preset time period is acquired, and the actual total generation amount is calculated; and the wind power loss cost in the preset time period is calculated and outputted, wherein the wind power loss cost=(the standard total generation amount-the actual total generation amount)*unit electricity cost. A standard for evaluating the maintenance scheduling scheme is provided, and the reasonableness of the evaluation standard is greatly improved. On the premise of meeting maintenance scheduling requirements, the maintenance cost is controlled to be the lowest.

Description

technical field [0001] The invention relates to the field of intelligent maintenance, in particular to a method and system for calculating and scheduling maintenance costs of offshore wind farms. Background technique [0002] Compared with the maintenance work of onshore wind farms, offshore wind farms face harsh environments such as tides, typhoons, air currents, and lightning. Units are prone to failure and maintenance is more difficult than onshore ones. Especially in bad sea conditions, maintenance personnel are difficult to access , the fault cannot be ruled out, especially the maintenance work of the unit in the deep water area is extremely difficult, which makes the operation and maintenance cost of the offshore wind farm higher. Due to the above reasons, the availability factor of current offshore wind turbines is also low, usually 80%-95%, and the maintenance cost is more than twice that of onshore wind farms, which means that the maintenance of offshore wind farms ...
