Development And Research Of HLA-based Substation Training Simulation System

With the rapid development of computer science and simulation technology, substation training simulation system which raises economic and safety level of the power department’s operation are applied widely in power system. Additionally, considering the complex structure and expanding scale of power net, power market’s evolution and the use of new technology, substation watchers need a new simulation platform which supports more features of power network to train and study.Referring to the factual requirement of power department, development of substation training simulation system and the High Level Architecture (HLA), a new method is given to build substation training simulation system. Using HLA, problems of the software reusability, openness and interoperability have been solved and the simulation system is enhanced.First, this paper introduces the background, development and current problems of substation training simulation system, and HLA solution is put forward. HLA is described in detail, including rules, management services and RTI. The system’s hardware structure, software structure, simulation range and the function are also described in detail.Second, according to the composition and characteristics of substation equipment, the paper focuses on federate division and its function. Designing object class, interaction class and publish/subscribe relations of FOM and SOM, elaborating on the federate synchronization, the creation, existence and destruction of federation execution, handling process of normal and fault events, structure of3d model of equipment and VRP scene.Finally, in order to ensure normal sequence of events in training, this paper deeply discusses the application of time management in simulation system, expounds the principles of time management, sets up the time management strategy and Lookahead of each federate, puts forward the method that system uses TAR in normal status and NER in fault status, and analyzes time advance process of each federate in normal status and fault status. Digital substation is the development trend in future, thus this paper puts forward the concept of digital substation simulation and the problems when simulated.
