Second, the power loss management and technical aspects of the main approach
Line loss management in the rural areas where electricity production technology management, management of the key. A direct impact on the economic efficiency of enterprises supply, power supply enterprises is an important economic indicator. To do this work, we must standardize their management and the formulation Film capacitor and improvement of corresponding measures, and a set of normal management order. How to strengthen the management of low-voltage line loss, the low-voltage lines to minimize loss rate, the electricity sector has become an important issue. The author attempts to integrate the actual situation of the company, talking about some superficial view.
First, the rural power grids of the reasons for the high loss
(1) network and equipment
2, intensify supervision and management and use, Anti-stealing Electric Power work to establish long-term mechanism. Developing an annual plan for the inspection of electricity, and seriously organize the inspection and electricity business census. The change to all users, including business files, check metering device at the scene, inspection, replacement of sealed lead, a new survey conducted seriously. On the census Film capacitor in the illegal use of electricity users metering box (cabinet) needs rectification require users with timely rectification. Lead clamp closure developed management methods, which provides electricity closure clamp closures lead directly managed by the director, and lead to closure of the closure clamp recipients records, a clear each location of the use of lead closure, sealed lead by the end of electricity supply by electricians and users were recorded in the closure lead signature on the registration form.
(B) to strengthen marketing and management and standardize procedures
1, in 2004 before the company only 110 kV Substation 1, the main transformer capacity of 2 ? 31.5MV A; 35kV10 Block, the main transformer capacity of 62.1 MV A weak power grid has been unable to meet the demands of economic development. To this end, the company increased grid connection of funding, have also completed a 220 kV substation, the main transformer capacity of 2 ? 180MV A, 110kV substation 4, the main transformer capacity of 189 MV A, 35kV substation nine, the main transformer capacity of 97.4 MV A, improved optimization of the network and layout. Central to the “Rise of Central China strategy,” the CPC Anhui Provincial Committee made “industrial powerhouse province” card, led by the information industry in the high-tech promotion of the economic strength has been continuously increasing, and Anhui information industry, “the military emblem of the” growing power. In the interview, reporters found, Anhui be fostered Industrial Park, the development of competitive industries, the implementation of major industrial projects, determined to break established the “11th Five-Year Plan” target and scale new heights.
1, in reactive power compensation to grade compensation, local balance, with a minimum of investment, access to the most economical of the main transformer substation switching, according to load to select the best way to guarantee the operation of safe operation and voltage quality, the reduction of the maximum power grid loss. The electricity distribution transformer on a monthly basis by the Taiwan Power Factor evaluate the the distribution transformer to propose remedial measures. Need technical transformation of the distribution transformer from the production of construction included in the plan for compensation. The substation at 10% to 25% with the main transformer capacity capacitor compensation device, scheduling grid voltage on the basis of the actual situation in various aspects substation capacitor determine the running and make a record.
Low-voltage lines in rural areas face more point-mismanagement, which are the cause excessive loss of the rural power grids major factors such as: theft, the phenomenon to happen Film capacitor even though more trees felled difficulties caused leakage, measurement meters can not be scheduled certification, the table can not fault the timely processing, resulting in Table of such measures can not be correct.
1, strictly enforce the copy, nuclear, system. From the source, starting with the establishment of sound files electricity users, strictly regulate user access to equipment, registration and temporary registration of electricity, and do a good job at stopping users, and marketing household registration and tracking management. County unified “copy, nuclear, or” management model. - Establishment of a sub-meter-reading classes, unified meter reading time, unified review time, the use of computer unified bill. Supervisor meter-reading classes with the company on the implementation of variable user Supervisor copied checks to ensure that the meter reading is copied rate to prevent leakage copied the wrong copy of phenomena such as occurred in strict accordance with the “copy, nuclear, or management approach” to see copied electricity 0.05% error rate in the control areas.
(D) strengthen the distribution network of reactive management, and improving the quality of the grid voltage
(B) management
(C) improve the planning and construction of power grids, the ability to improve economic performance grid

Line Loss management is a complex enterprise supply the important work of the management firm control of the company because of Loss Reduction, Technical Loss Reduction two measures, and increase the intensity of the line loss assessment, the management of the line loss has made great progress, and agreed State Grid Corporation awarded the “power loss in advanced power management enterprises.” comprehensive line loss rate of 8.53% over the same period last year declined by 1.58 percentage points, less accumulated loss of 6.56 million kW h of electricity, Loss Reduction achieved substantive results, further promote the economic development Film capacitor of the enterprise.
2, in order to guarantee power grid operation of the economy, has also formulated the “Operation management approach”, “and capacitor network operation and management methods”, “Film capacitor main transformer tap changer adjust management practices” and “Transformer economic operation and management methods” so that the grid is the economy the system guarantee. At the same time, out of a high-energy distribution transformer equipment, high energy distribution transformer equipment replacement, the distribution network technology update on the part of aging, small diameter of the 10 kV line to the improvement of their distribution transformer load management. By the regular monthly electricity distribution transformer to the pressure, flow measurement, the test load, and make a recording and analysis, optimization with variable layout, and appropriately adjust the distribution transformer capacity, improve distribution transformer loading rate on the three-phase load imbalance Distribution Transformer time to adjust.
To sum up, the rural power grids affected line loss was due mainly to the high management and technical aspects of the two, only two aspects of this, starting with the line loss management can achieve a reasonable level.
1, in accordance with the requirements of line loss management, and control the depletion of the rural power grids power management mode, I set up the company in accordance with the actual situation of the three line loss management network, the establishment of a general manager to head of the Leading Group for line loss management, formulate and perfect “Loss Management Measures”, “Line Loss assessment methods” so that the line loss more standardized assessment reasonable. And electricity supply company formed by the sale of a wholesale internal examination, a comprehensive index at line pressure, the Taiwan District implemented in each and every single employee. And the loss of work and staff salaries, bonuses linked to the completion of the monthly line loss indicators sector, the month the payment line loss assessment Fund (each person on line loss assessment fund: Film capacitor official = Kong-the personal factor ? ? 20 yuan ; agricultural electrician = Kong-class individual coefficient ? ? 7 million); did not complete monthly line loss indicators sector, the line loss Koufa month assessment funds, to complete the quarterly cumulative line loss assessment indicators sector, returning 80% detained Loss assessment of the amount due to incentives clear, the staff is fully aware of line loss assessment sense of crisis and sense of urgency. From the University of general practitioners by leaps and bounds
2, strengthen line loss analysis, a theoretical calculation of line losses. Establish two-loss analysis system. Power of the monthly line loss to the basis of the analysis, the company held regular monthly line loss of will and the occasional hold a special line loss management meetings, in accordance with line loss analysis, targeted to formulate quarter, and monthly Reduction Measures plan. Line Loss accounting contrast to implement three methods: compared with the previous month, compared with the same period last year, compared with the theoretical calculation. The theoretical basis, the Loss Reduction clear the main direction for the development of Loss Reduction Loss Reduction programme and annual plans and provide a basis for identification of the indicators.
3, standardized measurement management, solidified line loss management infrastructure. Energy Measurement Device accurate or not, the line loss rate is accurate or not the premise. To this end, the company has successively enacted the Energy Metering Installation and acceptance of management, operation and maintenance of electric metering device testing, energy metering devices running ledger, as well as electric metering device asset management, and other related systems. In addition, the failure of the transformer and meter out timely replacement of the user table clamp or locked box timely closure to ensure that the measurement accuracy. Called for a point of order by regular rotation meter calibration to ensure that the error was qualified to the extent possible within the scope of the installation position reasonable to shorten the distance feeders, feeder increase cross-sectional area.
At present, the tapping of more cleverly and gradually to the development of technology-based, in order to intensify the fight against theft of electricity, the company vigorously publicizing the law on the basis of electricity, often carry out large-scale or breach the Anti-stealing Electric Power electricity against theft and the destruction of power facilities, and other activities, with supervisors and personnel supply regular night attack by the staff, not to regularly inspect the scene measurement point in the pilot installation of a large number of remote users on-line management system, the user real-time monitoring, and system function and stability of a comprehensive test, and to effectively check the occurrence of the Fault Tolerant and Anti-stealing Electric Power and punish illegal electricity meritorious staff to be appropriate incentives, and safeguarding the company’s electricity market to normal operations.
Cong Da-ming said that in order to do a good job quality province, Shandong Province has made a comprehensive plan and some aspects of the preparatory work. Including major work on the brand, promoting industrial restructuring, the sectors with a competitive edge, first introduced to competitive industries through standards first, good energy emissions; seized promote science and technology to enhance their own capacity building.
Distribution network layout is not quite reasonable, too small a cross-section of the Lines, a long running time, the aging lines serious, high-energy larger proportion of distribution transformers, transformer configuration unreasonable, a low utilization rate, variable loss, “a big Malassezia Trolley “phenomenon, 3-phase 4-wire load imbalance, reactive power compensation was not complete.
