    • PURPOSE: A digital electric power substation adaptive protection operation system and a method thereof are provided to actively handle a dynamic change of a power system by performing protection operation for changes of the power system. CONSTITUTION: A data receiver(110) receives impedance data of a power system from a first intelligent electronic device set for monitoring a digital electric power substation. A power system change recognizer(120) determines changes of the power system by determining whether the data is changed or not. A correction value calculator(130) corrects the impedance data through a correction formula stored in a correction management database according to the changes. A setting group receiver(140) compares the correction value with a control value preset in one or more intelligent electronic devices. A setting group setting device(150) sets the control value as the correction value according to the comparison result.

    • PURPOSE: A substation automation system and a substation monitoring data obtaining method are provided to obtain high precision digital data by using a plurality of merging units performing AD conversion according to different measuring ranges. CONSTITUTION: A substation(10) includes a transformer(11), a bus line(12), a line(13), and a breaker(14). A current merging unit(210) includes a first current merging unit(211), and a second current merging unit(212). A voltage merging unit(220) generates voltage data by converting a received analog voltage signal to a digital voltage signal. The voltage merging unit transmits the voltage data to an IED(Intelligent Electronic Device)(230) through a process bus(250). An HMI(Human Machine Interface)(240) provides received monitoring data from the IED to a user.
