Method for calculating closed-loop rotation power supply control parameters

Abstract

The application discloses a method for calculating closed-loop rotation power supply control parameters. The method comprises the following steps: acquiring power distribution network equipment parameters; constructing a power distribution network optimization model according to the power distribution network equipment parameters; carrying out closed-loop rotation power supply calculation by virtue of the power distribution network optimization model based on a power flow calculation method, so as to obtain control parameters; acquiring preset parameters in a database; judging whether the control parameters meet the requirement according to the preset parameters, wherein if yes, a power flow control signal is generated and the power flow control signal is sent back to a dispatch monitoring system, otherwise, the step (1) is executed; and generating the power flow control signal, and returning the power flow control signal to the dispatch monitoring system. According to the method for calculating the closed-loop rotation power supply control parameters, the data required in the calculation process is acquired from the distribution network optimization model, so that a calculation result can truly represent current power grid operation conditions, and the current power grid operation conditions can meet the dispatch operation requirement.

Description

technical field [0001] The present application relates to the field of power system analysis, and in particular to a method for calculating control parameters of closed-loop switching power supply. Background technique [0002] my country's distribution network is mostly radial single-circuit wiring. When the line fails, the power supply needs to be cut off, which will cause a short-term power outage at the user end of the branch line, destroying the stability of the system power supply and failing to meet the user's requirements for power supply continuity. [0003] Ring closing operation refers to the operation of converting two or more distribution lines of the same voltage level from radial wiring to ring wiring by closing the tie switch under the condition of ensuring no power failure. As a new type of power supply mode, loop-closing transfer power supply does not require additional lines. When a fault occurs and a power outage operation is required, the connection swi...
