Title: SYSTEM FOR POWER TRANSMISSION LINE PERMITTED HEAT CAPACITY CALCULATION AND ELECTRIC POWER-SYSTEM ANALYSIS
Abstract:
A system for power transmission line permitted heat capacity calculation and electric power-system analysis is disclosed. The system for power transmission line permitted heat capacity calculation and electric power-system analysis comprises: an information acquisition module for acquiring ambient temperature information and power transmission geographical information; a heat capacity calculation module for calculating a maximum permitted heat capacity of a power transmission line on the basis of the ambient temperature information and power transmission geographical information received from the information acquisition module; a system analysis module comprising an electric power-system DB for storing information on equipment and states of the electric power-system, and a power flow analysis unit for calculating power flow volume for each power transmission line in order to analyze a state of the electric power-system; a cooperative analysis module for analyzing whether or not an overload is applied to the power transmission line in cooperation with the heat capacity calculation module and the system analysis module, wherein the ambient temperature information may include past daytime highest temperature observation information measured at a plurality of observation points.
