Research And Development Of The Upper Computer Monitor Software Based Power System Dynamic Simulation Experimental Platform

With the development of power system and the progress of physical simulation technology,power system dynamic simulation has become an important means to study the power system.Because fault test of power system can not be verified in the running equipment,the emergence of the dynamic simulation experimental platform provides great convenience for the teaching and research of electrical science.In order to cooperate with the hardware platform research and teaching,the development of a dynamic simulation laboratory for the upper computer sofeware is very necessary.Based on the experimental requirements of dynamic simulation laboratory,this paper takes Microsoft Visual Studio platform as software development tool and MFC as programming language,adopts C/S network communication mode,and develops a set of upper computer software which is used in the research and teaching for dynamic simulation laboratory,the main research work are in the following areas:First of all,the main interface of the host computer software can draw a system wiring diagram to simulate the actual connection of the laboratory electrical device,and design a database of graphic elements with the use of gallery model integration,besides the paper establishs the mapping relationship between the electrical device and SVG elements through the CIM model,and the mapping relationship between SVG elements and database through Hibernate framework;Secondly,communication channels between the upper computer machine software and PMU measurement device are established by the use of socket,and actual physical connection is established by the serial port to network device;Afterward,the thread function of MFC built-in library is introduced to establish the monitoring interface of waveform display and data display.The monitoring variables are displayed in the wiring diagram.The waveform interface can display real-time waveforms of various curves.Finally,according to the needs of laboratory data storage and calling,the database which stores PMU data,device informationand device connection information is designed for the upper computer machine software and the database table is stored by the ADO call.At present,the research group has completed the test for the mapping function,communication function,monitoring function and data storage function of the upper computer machine to ensure that these four functions can meet the standard of dynamic simulation laboratory for research and teaching.
