JPS6416221A - Stoppage regulation/calculation system for power system facility - Google Patents

Abstract

PURPOSE:To lighten the burden of an operator when the operator prepares discussion data necessary for stoppage regulation, by carrying out power flow calculation for the system condition on the operating day while separating a stoppage object facility and an imaginary fault facility sequentially from the system, thereby checking overload. CONSTITUTION:A calculation object system preparing section 8 separates data of stoppage object facility in a stoppage object facility data preserving section 3 from the data in an operating day system data preserving section 7, then feed base system data to a calculation object system preserving section 9 to execute power flow calculation through a stoppage regulation calculating section 10 and check occurrence of overload. Upon occurrence of overload, overload data are fed together with stopped facility data to a stoppage regulation calculation result preserving section 12. If overload does not occur, the preparing section 8 separates data of imaginary fault facility in the preserving section 5, then occurrence of overload is checked in the calculating section 10 and fed to the preserving section 12. The result thus obtained is fed from a calculation result edditing section 13 through a man machine device 1 to an operator.
