The invention discloses an optimization configuration method for a three-remote power distribution terminal. An explicit formula for computing reliability indexes is proposed by a mathematical model; the core is a formula for load point power-off time caused by fault points; the terminal optimization problem is extracted into an explicit mathematical model; by adopting nonlinear programming to resolve, a configuration scheme with higher quality is obtained; the optimization configuration method has higher engineering application value; by taking the system reliability as constraint and economic efficiency as a target, optimization configuration is performed on the number and positions of three-remote terminal units on a feeder line by the optimization configuration method for the three-remote power distribution terminal; the model contains the DSRATU (distribution system reliability analysis with terminal units) method of a power distribution terminal-contained power distribution system, and detailed reliability modeling and economic modeling; on the premise that the system has higher reliability, the optimization of the economic efficiency is realized; the optimization configuration method has both system reliability and economic efficiency, and has higher popularization and application value.
Description
Technical field [0001] The invention belongs to the technical field of power supply and distribution, and in particular relates to an optimized configuration method for a three-remote power distribution terminal. Background technique [0002] Various types of one-remote, two-remote, and three-remote are important parts of distribution automation, which are of great significance to the observation and fault handling of the distribution system. With the development of distribution automation, the transformation and construction of distribution network Must do. [0003] The two-remote terminal has the functions of reporting fault information (remote signaling of the switch status) and current telemetry. It does not have the remote control function, and the corresponding switch does not need to have an electric operating mechanism. The three-remote power distribution terminal has the functions of remote measurement, remote signaling, remote control and fault information reporting. [0...
