| 摘 要： | 根据对SCOTT变压器的电磁分析,推导出了其电压平衡方程,进而提出了基于变压器模型的保护理论、动作方程和动作特性,并指出了动作方程参数整定的指导原则。通过对SCOTT变压器在多种运行状态下的仿真计算,检验了该保护原理、动作方程、动作特性和整定原则的正确性。

| Abstract: | Based on the electromagnetics analysis of the SCOTT transformer, this paper derives its voltage equations and presents the transformer protection principle, operation equations and operation characteristics. The rules about how to set the parameters in the operation equations are proposed. The simulated results of the SCOTT transformer in different running states confirm the correctness of the protection principle, operation equations, operation characteristics and setting rules. |
