Problems solved by technology
At present, the construction of distribution networks in various regions of the country is developing rapidly, but the construction of distribution network automation systems is relatively lagging behind, and most areas are still in an environment without the support of distribution network automation systems. In the main station system of the distribution network, the problem of "blind adjustment" can only be solved reluctantly, and it is impossible to realize the research and judgment of switch fault tripping, alarm push and impact range analysis in the distribution network line

The invention discloses a distribution network line failure studying, judging and alarm analysis method. The distribution network line failure studying, judging and alarm analysis method comprises the following steps of: obtaining the ledger of distribution network equipment and the outlet load data of substations from a dispatching energy management system, and obtaining the ledger of the distribution network equipment and real-time load data of distribution transformers from a marketing electricity information acquisition system; storing the acquired data in a database; drawing a distribution network feeder model, calling the outlet load data of the substations and the real-time load data of the distribution transformer from the database, and furthermore, configuring at the dispatching substation outlet and the various distribution transformers of the distribution network feeder model; and, performing line failure studying, judging and analysis according to the topological structure of the distribution network feeder model and the called data, and giving an alarm when a failure is judged. By means of the distribution network line failure studying, judging and alarm analysis method disclosed by the invention, the distribution network structure and the equipment operation condition are reflected really and fully; furthermore, the abnormal condition and the influence range in a distribution network line can be judged rapidly and accurately; and the distribution network operation accident occurrence probability and the customer complaint rate are reduced.
Description
technical field [0001] The invention relates to the field of distribution network automation, in particular to a method for researching and judging and alarming analysis of distribution network line faults. Background technique [0002] Distribution network line fault judgment and alarm analysis is an important technical means and management means in distribution network automation. At present, the construction of distribution networks in various regions of the country is developing rapidly, but the construction of distribution network automation systems is relatively lagging behind, and most areas are still in an environment without the support of distribution network automation systems. In the main station system of the distribution network, the problem of "blind adjustment" can only be solved reluctantly, and it is impossible to realize the research and judgment of switch fault tripping, alarm push and impact range analysis in the distribution network line.
