Description

technical field [0001] The invention belongs to the technical field of power systems, and relates to a PSD-BPA-oriented method for quickly generating models of wind farm collector lines, box transformers and generator sets. Background technique [0002] PSD-BPA is a power system simulation analysis software launched by China Electric Power Research Institute. Power system technicians usually use PSD-BPA as a simulation tool when carrying out planning and design, scientific research, and equivalent modeling for wind farms. At present, the conventional method of establishing a wind farm simulation model based on PSD-BPA is to manually establish data cards describing various equipment models in BPA based on collected information such as collector lines, box transformers, and generator sets. This method has a large workload, relatively low efficiency, and a high probability of error. The main reason is that there are many generator sets in the wind farm, and some even have hund...

Problems solved by technology

This method has a large workload, relatively low efficiency, and a high probability of error. The main reason is that there are many generator sets in the wind farm, and some even have hundreds of them. When modeling, it is necessary to establish a corresponding Node card and dynamic model card; there are many branches in the collector line, and the per-unit value of the line model parameters needs to be calculated according to the length and physical parameters of each line when modeling, and a data card is established for each line; matching with the generator set There are many box-type transformers. When modeling, it is necessary to calculate the per unit value of the model parameters according to the physical parameters of each box-type transformer, and create a data card for each box-type transformer.

[0003] Although there are a large number of collector lines, box transformers, and generator sets in a wind farm, analyzing their characteristics shows that in a wind farm, there are generally only a limited number of collector line models, and box transformers and generator sets are also Yes, but there is currently no existing technology to integrate it into simulation models
