Auxiliary control system for economical operation of regional electric network transformer

Abstract

The invention relates to an auxiliary control system for economical operation of a regional electric network transformer, which is applied to the technical field of electric power. The system comprises a database module, a communication module, an analysis and calculation module, a graphic display module, a report management module and a system management module, wherein the input end of the communication module is respectively connected with an automatic dispatch system and the analysis and calculation module to receive the measured data and form an economical operation control policy and an optimized operation curve to be output to the system management module, the graphic display module and the report management module; the database module is connected with the communication module to transmit the measured data; and the output end of the database module is connected with the analysis and calculation module to transmit the measured data, the economical operation control policy and the optimized operation curve. The invention can realize the purpose of controlling the overall process to be completed automatically, can greatly reduce the working strength of field operators, reduce the network loss and increase the power factor at the load side of the electric network, and has positive significance of energy saving and consumption reduction for the whole electric power system.

Description

technical field [0001] The invention relates to a system in the field of electric power technology, in particular to an auxiliary control system for economical operation of regional grid transformers. Background technique [0002] Transformer is a widely used energy-consuming equipment in the whole national economy and people's livelihood, and it is also the main electrical appliance in the process of electric power production. When the transformer transforms voltage and transmits electric power, it will generate active power loss and reactive power consumption. Due to the large number of transformers and the large total capacity, the total power loss of transformers in the process of power generation, supply and consumption accounts for about 30% of the loss of the entire power system. Therefore, comprehensively carrying out the economic operation of transformers is an important link to realize energy saving, loss reduction and economic operation of the power system. [0...

Problems solved by technology

However, this existing technology only deals with the case of two double-coil transformers, and does not involve the situation of three-coil transformers, so the scope of application is limited; in addition, this technology only uses the current load data for analysis, and does not take into account the load of the regional power grid. Historical data does not have the function of load forecasting based on historical data, so it is impossible to make reasonable and accurate arrangements for the economic operation mode of transformers in the future
