Study And Realization Of Optimizing Operation Mode And Reducing Network Loss Rate In County Power Grid

The power network power loss rate is an important and comprehensive technical and economic indicator for power grid production and operation companies.It comprehensively represents the planning and design level,production management level,and operation and management level of the power system.During the process of the transmission of electrical energy from the power plant until it is delivered to various power users,power losses are generated inside the equipment such as power generation,transmission,transformation,and distribution.Since such loss of electric energy is unavoidable,it must be limited to a reasonable range through scientific and reasonable technologies and management measures.The economic operation of the power system is mainly to determine the best combination of the unit and to distribute the load economically.At this time,the system-wide economy is considered,and line loss is not a decisive factor.Therefore,under the premise of economical allocation of active power of the system,the economic operation of the power grid and its equipment is an effective measure to reduce line losses.The operating mode of the power grid refers to the method and form of operation of the electrical equipment,including the operating status of the equipment such as transformers,capacitors,lines,switches,disconnectors,grounding switches,etc.(operation status,hot standby status,cold standby status,and maintenance status)as well as the form(such as the number of transformers to run and mode-run in parallel,run in separate columns).The operating mode not only concerns the safe operation of the power grid,but also is closely related to the network loss.Scientifically and reasonably adjusting the operation mode can reduce the network loss as much as possible under the premise of ensuring safe operation.This requires comprehensive application of line loss theory calculations,loss reduction techniques,energy metering,error theory and data processing,and even management science and technology.This paper is based on the background of A county power grid.Firstly,it analyzes county power grid operation,development and construction,weak links,reactive power and balance between supply and demand in A county.Based on the development and construction of county power grid in A county,the scale of power grid,and its important equipment The inspection and repair methods have been analyzed and researched.Based on the above work,the research,simulation and practical application of how to reduce the net loss under the premise of ensuring the safe operation through scientific and rational adjustment of the operating mode are focused.Application practice shows that the scientific and rational adjustment of its operation mode can reduce its network loss by 0.5%.Reasonable adjustment of operation mode can optimize the power grid to some extent.The results of this paper can be applied to county grids with similar grid structure,which can help reduce grid losses,reduce energy consumption,and increase economic efficiency.The experimental data in this paper comes from the real-time data of the A county power grid.It is impossible to completely repeat the historical parameters due to the operating parameters of the grid,and it is impossible to carry out comparative tests in absolute sense.Therefore,the conclusions obtained are ambiguous and similar.In the future,with the improvement of the simulation system,a comparative test can be performed on the simulation system,which can be used to better revise the conclusions so as to facilitate the further popularization and application of research results.
