Test method and tester for distributed power distribution network

Abstract

The invention relates to a test method for a distributed power distribution network, the power distribution network comprises a plurality of power distribution network nodes and testers corresponding to the power distribution network nodes, the testers are connected with corresponding power distribution network terminals, and the method comprises the following steps: collecting circuit breaker position information of a current power distribution network node in the plurality of power distribution network nodes; receiving circuit breaker position information and power distribution network architecture information of other power distribution network nodes different from the current power distribution network node in the plurality of power distribution network nodes; and calculating and outputting the analog quantity of the current power distribution network node based on the position information of the circuit breaker of the current power distribution network node, the position information of the circuit breakers of the other power distribution network nodes and the network architecture information of the power distribution network. The invention also relates to a tester distributed in the power distribution network. According to the power distribution network terminal test method, the complexity of the test process is reduced, the overall efficiency of the system test is improved, and the requirements of the power distribution network system test are met.

Description

technical field [0001] The invention belongs to the field of power systems, in particular to a testing method and a testing instrument for a distributed distribution network. Background technique [0002] At present, for the distribution network of the power system, considering the importance of load, investment scale and other factors, there are various wiring methods such as radiation type, single ring network type, double ring network type, N supply and one backup type, and petal type. [0003] Radial wiring is simple, low investment, and high equipment utilization, but there is only one power point. After a fault, the fault point and the load are cut off at the same time, resulting in low power supply reliability. Single-ring network type, double-ring network type, N-supply-one-standby type, and petal type reduce equipment utilization and increase investment. When the distribution line fails or is overhauled, the load can be reconnected to the power supply by changing th...
