PROBLEM TO BE SOLVED: To improve the operability by reducing the load of communication network by receiving a program module in response to a display operation from a display operation equipment by the protection controller and by returning the results of execution or a program module received to a protection controller or transferring to other protection controller. SOLUTION: A digital type protection controller 10 performing the protection control of a power system 1 comprises program module receiving means 11, execution means 12, and execution results and program module returning and transferring means 13. And it receives a program module comprising data and procedures unified corresponding to the contents of the display operation from a display operation equipment 20 through a communication network 30, returns its execution results to the display operation equipment 20 or transfers the received program module to other digital type protection controller 40. By doing this, the traffic of the communication network 30 can be reduced, the amount work by the operator can be reduced, and the economy and operability can be improved. |
