Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] Such as figure 1 As shown, a method for monitoring distributed power grid-connected in a distribution network terminal includes the following steps: a. The distribution network terminal collects distributed power grid-connected feeder data; b. The distribution network terminal processes the collected data to obtain the power quality status ; c process the grid-connected state of the distributed power supply. Through the detection of the power quality of the distributed power system, it is possible to separate the distributed power grid-connected system and the power distribution network when there is an out-of-limit situation that deviates from the standard, so as to avoid affecting the normal operation of the power distribution network. At the same time, the distributed power system can be notified of the status, so that the distributed power generation system can ...

Abstract

The invention relates to the technical field of electric power supply / distribution and discloses a method for monitoring distributed power supply network incorporation in a distribution network terminal. The method comprises the following steps of: (a) acquiring feeder data of the distributed power supply network incorporation by using the distribution network terminal; (b) processing the acquiring quantity by using the distribution network terminal to acquire the quality condition of electric energy; and (c) processing the state of the distributed power supply network incorporation. The method has the advantages that: through the detection on the quality of the electric energy of a distributed power supply system, a distributed power supply network incorporation system can be separated from a distribution network when out-of-limit condition deviating from the standard occurs so as to avoid the influence on the normal operation of the distribution network; and at the same time, the condition can be notified to the distributed power supply system so that the distributed power supply system can perform the corresponding processing in time.

Description

technical field [0001] The invention relates to the technical field of power supply and distribution, in particular to a method for monitoring distributed power grid connection in a distribution network terminal. Background technique [0002] The power industry standard DL / T 721-2000 "Distribution Network Automation System Remote Terminal" defines the distribution network automation system remote terminal as: the distribution network automation system remote terminal is used for various distribution network distribution circuits The general term for equipment such as power remote terminals, distribution transformer remote terminals, and medium-voltage monitoring units (distribution automation and management system sub-stations). The communication channel is used to complete functions such as data collection and remote control. Distributed Generation (DG for short) refers to the economical, efficient and reliable power generation using small and medium-sized power generation...
