【Abstract】 In order to intensify comprehensive experiments of power system,a comprehensive laboratory model for large-scale physical simulation of power system is devised.The primary system of the model which can simulate the normal/abnormal and fault operations in various structural modes of power system is composed of an infinite-bus system,generators,transformers,lines,load points and facilities for short-circuit faults.The secondary(monitoring) system of the model can achieve real-time and synchronous measurement,control,wave recorder and graphic display.The protection system is equipped with microprocessor-based high frequency protections,feeder line protections,and transformer protections.The laboratory model has integrated all the experiment items and therefore can improve the students’ abilities in engineering practice and innovation.更多还原
