摘要
为了适应目前继电保护的高可靠性、选择性与灵敏度的要求,提出运用PSCAD和Python软件相结合的数字式继电保护仿真方法。在PSCAD软件中搭建双端电源距离保护模型,在Python软件对故障选相、继电器动作逻辑进行程序设计,实现距离保护功能。
In order to meet the requirements of high reliability,selectivity and sensitivity of current relay protection,a digital relay protection simulation method combining PSCAD and Python software is proposed.The model of distance protection of double-terminal power supply is built in PSCAD software.The fault phase selection and relay action logic are programmed in Python software to realize the function of distance protection.
