The invention discloses a dynamic reactive compensation response time calculation method and device and computer equipment, and is applied to an electric power system, and the electric power system comprises a dynamic reactive compensation device which is connected with a first output end of an electric power transmission line through a transformer; the second output end of the power transmission line is used for being connected with a load. The method comprises the steps that first power operation data of the load and second power operation data of a transformer access point are acquired; calculating a first reactive power before the step of the load and a second reactive power after the step of the load based on the first power operation data and the second power operation data; determining a start moment of step response time based on the actual reactive power of the load, the first reactive power and the second reactive power, and determining an end moment of the step response time based on the actual reactive power of the load and a preset power range; and determining the dynamic reactive compensation response time based on the starting time and the ending time.
Description
technical field [0001] The invention relates to the technical field of dynamic reactive power compensation technology, in particular to a calculation method, device and computer equipment for response time of dynamic reactive power compensation. Background technique [0002] At present, dynamic var compensation devices mainly include static var compensator (static VARcompensator, SVC), static synchronous compensator (Static synchronous compensator, STATCOM) and fast dynamic response synchronous condenser (fast dynamic response synchronous condenser). [0003] The static var compensation device is a parallel controllable reactive power compensation device composed of static components, which adjusts the output by changing its capacitive or (and) inductive equivalent impedance to maintain or control specific parameters of the power system (typical parameters are voltage, reactive power). [0004] The power industry standard DL / T 1010.1-2006 "High Voltage Static Var Compensati...
