Problems solved by technology

[0006] Second, it is difficult to conduct reliability tests and evaluations on the operating characteristics and control performance of actual wind farms, because there is usually a lack of corresponding direct test data corresponding to actual wind farms
Even if there is corresponding direct test data, there are problems mentioned in the first limitation above
[0007] Third, the simulation and actual measurement are separated, and there is a problem that the simulation data and the actual measurement data are not synchronized, which has a negative impact on the test and evaluation of the operating characteristics and control performance of the wind farm, and also increases the burden of data storage and processing.
For example, wind turbine manufacturers are restricted from developing and testing wind farm optimization technologies, and wind power operators are restricted from evaluating and applying wind farm optimization technologies, etc.
These problems have hindered the development and application of wind farm optimization technology, hindered the wind power industry's standardization process for wind farm operating characteristics and control performance testing and evaluation, and restricted the high-quality development of the wind power industry

Description

technical field [0001] The invention belongs to the technical field of new energy power generation, and in particular relates to a wind farm real-time testing and evaluation system and method thereof. Background technique [0002] At present, the wind power industry is becoming more and more stable, and wind power technology is improving day by day. No matter in terms of quantity or quality, wind power has made great progress. However, as an unstable energy source, large-scale integration of wind power into the power system also brings problems that cannot be ignored, such as increased short-circuit capacity, deterioration of power quality, and poor system stability. As the penetration rate of wind power continues to increase, on the one hand, the impact of wind power on the security and stability of the power grid is becoming more and more obvious, which cannot be avoided. On the other hand, the power grid also puts forward more and more stringent requirements on the grid-...
