PROBLEM TO BE SOLVED: To easily further quickly and surely perform confirmation of a transmission part and an arithmetic part in a protection control device and a data delivery test between the protection control device and a data receiving device. SOLUTION: A protection control device 1 fetches an input data 2 of voltage information, current information, equipment information, etc., in an electric power system from an input part 3, and performs conversion calculation or the like from the input data 2 to a transmission data 6 in an arithmetic part 4. In the case of switching a changeover switch 8 to a side of the arithmetic part 4, its result is transmitted to a data receiving device 12 from a transmission part 5. In the case that the changeover switch 8 remains switched to the side of a simulation data 7, the simulation data 7 built in the protection control device 1 is input to the transmission part 5 to be transmitted therefrom to the data receiving device 12. In this way, even in the case that the input data 2 can not be fetched by the protection control device 1, a fixed value can be transmitted as a data to the data receiving device 12 from the transmission part 5. |
