Fault processing method for power distribution network of oil field

Abstract

The invention relates to a fault processing method for a power distribution network of an oil field. The fault processing method comprises the steps of seeking a position of a fault point when a fault occurs in the power distribution network of the oil field; disconnecting a circuit of the power distribution network of the oil field by the fault point, and judging whether the fault is a non-permanent fault or not; recovering connection of a disconnection point if the fault is a non-permanent fault, and starting oil pumping unit set in a circuit disconnected with a bus in batches; and otherwise starting a power generator of the oil pumping set nearest to the disconnection point on the circuit disconnected with the bus, and providing an active power for the circuit disconnected with the bus. After the circuit fault is detected, corresponding fault processing is performed according to a type of the fault, so that normal working of the oil pumping unit set can be guaranteed.

Description

technical field [0001] The invention relates to a fault processing method for an oil field distribution network. Background technique [0002] In the prior art, the oil field distribution network generally adopts a single power supply, and transmits and distributes power for the pumping units through a radial network structure. Multiple pumping units are connected in series to the main bus. The voltage drop at the end of the distribution line is very large, and the voltage of the pumping unit at the end of the line is low, which cannot meet the normal work requirements; while multiple pumping units are connected in series to the main bus, when one of the pumping units fails, it will As a result, the follow-up pumping units cannot work normally, and even cause a power outage on the entire line in severe cases, and the power transmission and distribution performance is unreliable. Contents of the invention [0003] The technical problem to be solved by the present invention...
