Transformer load management and control method

Abstract

The invention discloses a transformer load management and control method. The method comprises the steps of: collecting transformer operation information; acquiring power grid operation information; establishing a historical transformer operation database, and obtaining associated data related to the transformer load to form a historical sample set; based on the historical data sample set, utilizing SVM training to obtain a transformer load prediction model; obtaining the actual load of the transformer at a certain moment by using a least square method; judging and correcting the transformer load condition information data, and judging whether the data is abnormal or not; automatically issuing abnormal data by a provincial transformer load condition comprehensive monitoring platform main station; calculating a transformer load characteristic judgment basis in the judgment period, and judging whether the transformer is overloaded or overloaded or not; and when the transformer is evaluated as an overload transformer or an overload and heavy-load transformer, managing and controlling the overload of the transformer. The technical problems that in the prior art, no effective managementand control scheme is provided, and consequently later transformer faults happen, and safe power transmission is affected are solved.

Description

technical field [0001] The invention belongs to transformer monitoring technology, in particular to a method for monitoring and controlling transformer load conditions. Background technique [0002] As an indispensable energy source in today's world, the demand for electric power resources has grown steadily and rapidly during the transformation and development of the national economy. The development and construction of my country's power grid has also entered the implementation stage of the strategic project of "power transmission from west to east, north-south protection and supply, and national networking". However, China has a vast territory and uneven regional development. The speed of power grid construction in some areas is still relatively lagging behind. The continuous and rapid growth of power load has led to an increasing gap between the actual power supply capacity of the system and the power demand of users. Therefore, The system is often in a state of high lo...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: to provide a transformer load management and control method to solve the problem that the existing technology cannot effectively judge the integrity and correctness of the transformer load data; For data verification and control, the layered and hierarchical control mode is not adopted, and the abnormal data processing is poor in pertinence, effectiveness and timeliness; at the same time, the existing heavy overload judgment only relies on the current criterion, and the lack of comprehensive criteria makes the heavy overload judgment inaccurate , and the existing technology does not provide effective management and control schemes for transformers that are judged to be overloaded or overloaded, resulting in technical problems such as transformer failures affecting safe power transmission in the later stage
