Problems solved by technology
The process is cumbersome, time-consuming, error-prone, and there is no objective and unified standard. Therefore, an automatic test platform is needed to evaluate the accuracy of the developed algorithm.
The test of the fault diagnosis algorithm can be completed in the real-time data simulator (RTDS), but this method is cumbersome to operate and the test cost is high
Using PSCAD to generate simulation scenarios, the existing multiple operating mechanisms in PSCAD allow users to change controller gain or fault type, which can meet the requirements of PSCAD batch simulation to a certain extent, but this method is not flexible enough, and specific simulation needs to be added element

The invention discloses an automatic test platform and method for a fault diagnosis algorithm of a distribution network and application of the automatic test platform and method. The method comprisesthe steps that a PSCAD automation library is called through a Python script file, elements in a PSCAD simulation model are abstracted, control of the simulation model is achieved, and fault simulationexamples are generated in batches to form different simulation scenarios; fault recording data of all simulation scenarios is circularly read in and parsed, according to fault scenario information, input and element parameter information of the simulation examples are modified, fault diagnosis algorithms are operated, diagnosis results are obtained, diagnosis types and fault region information are stored and comprehensively compared with model information corresponding to a fault recording file, the accuracy of the corresponding fault diagnosis algorithm is obtained, and a test report is generated.
Description
technical field [0001] The disclosure relates to an automatic testing platform, method and application of a distribution network fault diagnosis algorithm. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] In recent years, as a large number of random and fluctuating distributed power sources are connected to the distribution network, the fault characteristics of the distribution network have undergone fundamental changes, and it is necessary to develop new fault diagnosis and location algorithms for active distribution networks. According to the classification of research objects, fault diagnosis is divided into diagnosis of equipment and diagnosis of power system. The fault diagnosis for equipment is to judge whether the system equipment is normal through comprehensive analysis of various information, and the fault diagnosis for the syste...
