Study On The Transformation Of Reactive Power Compensation For TaiZihei Power Supply Company

This paper analyzes the development of reactive power compensation and the status quo of research at home and abroad,as well as the national grid and related industrial policy, and analyzes the power status of Taizihei power supply company,obtained for reactive power compensation transformation of Taizihei power supply company is accord with national economic benefits,and listed on the technology is completely feasible.Through the analysis of reactive power compensation theory and the present situation of technology,based on the line of Taizihei power supply company,the node,power supply radius is too long,uneven load distribution characteristics,selected the total compensation capacity and 45 groups of 12.15 million the rod of the lack of reactive power compensation.Through the analysis of multiple line loss rate abnormalities,and the abnormal line loss rate sand lines line of sand king lines,line of zhu hou also has carried on the line.Transform average power factor is 0.87 after operation,the average line loss rate remains as high as 10.14%,the highest power factor is 0.91,also confirmed the stem it is difficult to accomplish the target of 0.95 power factor compensation method,low voltage line set the power factor of 0.92 is relatively reasonable,and should be appropriately adjust the reactive power compensation capacity.Article 13 in the circuit to reduce the total loss of up to 830 kw.And analysis using reactive compensation at the same time to great line,the sand trunk line,line of sand king lines,line of zhu hou has obtained certain result.And forecast the subsequent transformation is expected to further line can achieve the goal of line loss rate reached 9%.The project line loss rate up by more than 2%,with a total investment of 2.2254 million yuan,the annual revenue of 7.628 million yuan,the total benefits 5 years is about 35.471 million yuan,has a huge economic and social benefits.In this paper,the research results can be used for the high line loss rate in rural power grid design and reference.
