Description

technical field [0001] The invention belongs to the technical field of power systems and automation thereof, and more precisely relates to a safe and stable multi-algorithm packaging process custom configuration method for power systems. Background technique [0002] The stability of power system includes static, transient, dynamic and long-term stability, and each stability analysis corresponds to one or several calculation algorithms. For the same stability, even if the same algorithm is used, the analysis and calculation software provided by different software manufacturers are different. Various algorithms are relatively independent and interdependent. Some algorithm software analysis results need to be used as the input of other algorithm software, some algorithm software analysis results need to be used as trigger conditions for other algorithm software, and in some cases, several algorithms need to be coordinated to obtain the final result. Therefore, whether it is ...

Problems solved by technology

[0005] The above-mentioned invention patents cannot be directly applied to the packaging of multi-algorithms for power system security and stability. The reasons are as follows: First, the algorithms for power system security and stability analysis are not a single serial process, and there are both serial relationships and parallelism between the algorithms. Therefore, the sequential flow control method in Document 1 cannot be fully applied; the second is that the power system security and stability analysis requires interactive iterations of multiple algorithms, and the results of some algorithms may be used as trigger conditions for other algorithms to start. What calculation algorithm should be used in the next step? , needs to be determined according to the analysis results of the previous step, and the calculation environment parameters are dynamically changing and cannot be pre-defined through the prior configuration file. Therefore, the method of independently configuring the module file in advance and saving it as a file set in Document 2 is not applicable
