摘要： A system and method for determining a reliability line rating for a transmission line is disclosed. In response to a line clearance measurement and a line temperature measurement received from a transmission line monitor coupled to a transmission line, the system generates a temperature-clearance model for the transmission line based on the received line clearance measurement and line temperature measurement. The system generates a plurality of past dynamic line ratings and determines a scaling factor based on the plurality of past dynamic line ratings. The system then generates a dynamic line rating for an interval of time in the future and scales the dynamic line rating in response to the scaling factor to obtain a reliability line rating for the interval.

摘要： Provided is a power system stabilization system (1) capable of suppressing computation resources while maintaining computation accuracy for evaluating a state of a power system. A power system stabilization system (1) includes a power system computation unit (2) that receives a power system state, a power system model, and an event case as inputs and executes at least one of simple event computation and event computation, and a margin setting unit (3) that receives a margin setting parameter as an input and calculates a screening margin from a result of the simple event computation and a result of the event computation for an event case targeted by the power system computation unit (2). By the margin setting unit (3) calculating the screening margin from the results of both the simple event computation and the event computation, a possibility of erroneous screening can be curbed to maintain the computation accuracy, a system state of an evaluation target can be reduced according to power flow computation, and computation resources can be suppressed.
