The method specifically comprises the following steps: acquiring dynamic power curves of a unit before and after transformation, a single unit forecast table, and minute-level wind speed and generating capacity data recorded by an SCADA (Supervisory Control and Data Acquisition) system; calculating unit generating capacity caused by local average wind speed difference before and after transformation; calculating the actual generating capacity in the evaluation period before and after transformation; calculating the generating capacity lost due to the fact that the unit cannot be connected to the grid due to power grid faults and power limitation before and after transformation; calculating the generating capacity of unit loss caused by human factor shutdown before and after transformation; and finally, calculating the generating capacity and generating capacity increase rate of the unit in the evaluation period before and after transformation. The influence of unstable wind speed, power grid faults, human factors and the like on the generating capacity of the wind turbine generator is fully considered, and the accuracy of generating capacity evaluation before and after unit transformation is improved.
Description
technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a method, system, equipment and medium for evaluating the power generation increase rate before and after unit transformation. Background technique [0002] In recent years, the installed capacity of wind turbines in my country has continued to rise, the development of wind power technology is changing with each passing day, and new technologies and methods in the field of wind power are constantly emerging. In order to improve the performance of wind turbines, reduce operation and maintenance costs, and increase the power generation of the turbines, wind power operators have an increasingly urgent demand for technical transformation of wind turbines that have been put into operation in the early stage. [0003] At present, when wind farms evaluate the power generation of the units before and after the transformation, they usually use the method of compa...
