The Electric System Dynamic Simulation Lab was put into operation in 1961 and the Institute of Electrical Engineering was established by the approval of Ministry of Higher Education in 1963. The length of undergraduate schooling changed a lot in this period. It was five years of schooling for the undergraduates of 1958 and 1959, five and a half years for the undergraduates of 1961 and 1962, and six years for the undergraduates of 1964 and 1966. Two sessions of cadre training classes were held for industrial sectors from 1958 to 1959, with two years of schooling. In this period, a total of 180 ~ 200 students were enrolled as undergraduates every year. In addition, some overseas students were recruited from such countries as Korea, Viet Nam and Laos.
