Embodiment

[0136] Taking a certain wind turbine as an example, this embodiment provides a method for evaluating the reliability of a wind turbine, which specifically includes the following steps:

[0137] Step 1. According to the 14 state boundaries of wind turbines, summarize the ranges of operation, availability, planned outage, and unplanned outage, as shown in the table below.

[0138] Table 1. Operation status of wind turbines to be evaluated

[0139]

[0140] It can be seen from Table 1 above that the state boundary range of wind turbines to be evaluated includes: operating state range, standby state range, planned outage state range, unplanned outage state range and offline state range; where the operating state range includes normal power generation state, alarm power generation state, dispatching power cut state, abnormal power cut state and standby state; the standby state range includes power cut shutdown state, on-site involvement state, off-site involvement state and weat...

Abstract

The invention discloses a wind turbine generator reliability evaluation method, system and device and a readable storage medium, and the method comprises the steps: determining the operation state of a to-be-evaluated wind turbine generator according to a reliability dimension; obtaining a state boundary range of the to-be-evaluated wind turbine generator; according to the state boundary range of the to-be-evaluated wind turbine generator, calculating operation hours, standby hours, available hours, planned shutdown hours and non-planned shutdown hours of the to-be-evaluated wind turbine generator; calculating a reliability index of the to-be-evaluated wind turbine generator according to the operation hours, the standby hours, the available hours, the planned shutdown hours and the non-planned shutdown hours of the to-be-evaluated wind turbine generator; and ranking the to-be-evaluated wind turbine generators according to the reliability indexes of the to-be-evaluated wind turbine generators, and obtaining the reliability evaluation result of the to-be-evaluated wind turbine generators according to the ranking result. According to the method, the wind power reliability evaluation is finer and more effective, the unification and centralization of wind power plant group management are promoted, and a solid technical support is provided for intelligent wind power operation.

Description

technical field [0001] The invention belongs to the technical field of wind power, and in particular relates to a reliability evaluation method, system, equipment and readable storage medium of a wind turbine. Background technique [0002] At present, the reliability evaluation of wind turbines is mainly based on planned outage coefficient, unplanned outage coefficient, operation coefficient, availability coefficient, gross capacity coefficient, utilization coefficient, output coefficient, unplanned outage rate, unplanned outage occurrence rate, exposure Rate, average continuous available hours, average trouble-free available hours and other indicators. The above indicators are calculated based on the traditional six states of operation, failure, standby, maintenance, offline and power cut in the wind power industry. As a result, it is impossible to calculate the boundary range of each indicator. Clear and accurate definition, for example, it is impossible to judge whether t...
