The invention relates to a real-time measuring method for time-varying power of an electrical power system, which comprises the following steps of: collecting electrical signals u (t) and I (t) on a connector; measuring a first voltage parameter coefficient Au (t), a second voltage parameter coefficient Bu (t), a first current parameter coefficient Ai (t) and a second current parameter coefficient Bi (t); obtaining sine expressions of the electrical signals u (t) and I (t); and therefore, accurately measuring time-varying active power P (t) and time-varying reactive Q (t) of each moment on the connector. The method provided by the invention can be used for accurately measuring the time-varying active power and the time-varying reactive power of a periodic electrical signal or an aperiodic electrical signal in real time with the accuracy being above 98 percent, and can lay a solid foundation for reactive power compensation and security control of the electrical power system.
