Abstract

The invention discloses a method for evaluating the operation and maintenance level of a wind power plant, and the method comprises the following steps: 1), constructing the design parameter information table of all fans in the wind power plant, and obtaining the wind speed and air density of an environment where each fan is located in a statistical time period and the historical data of the state of each fan; 2), calculating the wind power in the statistical time period; 3), obtaining the time information of usable states of all fans in the statistical time period; 4), calculating corresponding usable wind energy when all fans are in usable states in the statistical time period; 5), calculating the total wind energy of all fans in the statistical time period; 6), calculating the energy utilization rate index EAF of each fan; 7), calculating the energy utilization rate index EAFs of the wind power plant; 8), obtaining the operation and maintenance level of the wind power plant according to the energy utilization rate index EAFs of the wind power plant at step 7). The method can accurately evaluate the operation and maintenance level of the wind power plant.

Description

technical field [0001] The invention belongs to the field of wind farm operation and maintenance, and relates to a method for evaluating the wind farm operation and maintenance level. Background technique [0002] For a long time, the availability of wind turbines (and the availability of wind farms) has been an important indicator for evaluating the operation and maintenance level of wind farms. It is also the wind power production and operation index system formulated by each power generation group, which is widely used as an index to evaluate the level of equipment management (operation and maintenance). The availability index follows the basic principle of equipment evaluation in the thermal power and hydropower fields: count the duration of various available states of the unit within a certain time range, and then calculate the proportion of the total duration of the available state. [0003] However, wind power is very different from thermal power and hydropower. As a...
