Application of User-defined Technique of PSS/E in Power System Transient Analysis

In spite of its rich model library,PSS/E can not meet the needs of the real industry development.Therefore,studying and grasping its user-defined(UD) technique is necessary.The application of UD technique of PSS/E in transient analysis is introduced in detail,the process of this technique was introduced by establishing the IEEE2 Governor model.To illustrate the general use of the technique,a voltage regulator in PSASP model library is written,whose accuracy has been verified in both single-infinite-bus system and three-generator-nine-bus system fully.
