       A rural power grid, the present situation of the reform

       In today's information, digital society, people's life is dying leave no electricity, but in 1998 years ago China's rural there are generally "RenQingDian", "rights electricity", "GuanXiDian" and "fees" and "random tariffs" "recourse" bad style. At the same time because the rural power equipment is general ageing, line loss huge, leading to the life not only exist in a lot of potential safety problems, and will also unnecessary power operation cost in the price of electricity to rural apportion, so that increased the farmers' burden, cause electricity, and there is electricity can't use, these are seriously restricts the development of local economy and the improvement of living standards of people. By the end of 1998, more than $1800 state approval as rural reconstruction funds, started large-scale urban and rural power grid construction and renovation. By 2003 the transmission and distribution level in China is had the very big enhancement, line loss rate decreased obviously. At the same time, according to the "two change pricing" principle, greatly reduce the burden of the peasants, and improve the quality of life of the well-off farmers, promote the rural electric power consumption and economic development, and push the development of all walks of life, to speed up the development of the rural market.

      B the rural power supply management problems

      (1) NongDianGong personnel quality low, management loose. At present there are NongDianGong personnel quality low, management is not in place of the phenomenon, go on like this would cause bad management, and line loss net rapid rise, reporting data false, accidents processing is not seasonable, these are low voltage power grid management in the prominent problem.

      (2) the rural user watt-hour meter and table and the transformation rate last line the phenomenon is quite common and prominent. Households table transformation is rural reconstruction project of the last link is also a key link, the direct impact on rural reform the economic benefits of the play after the level of security and rural electricity, its important meaning of the power supply enterprise is self-evident. But for a variety of reasons, the rural households table reconstruction work serious lag in the renovation of the circuit, and the influence of different level to the role of the article should be transformed. Watch junior door line no basic transformation, to the rural security electricity leaving many hidden trouble. Figures showed that some rural electrification transformation except some demonstration village form junior door outside line, accounting for 80% of the total number of the farmer households are not nearly line transformation. Low voltage grid power supply of reform are to raise the reliability, but with thousands of personal safety is door line in there is a lot of problems; Line old ageing, insulation performance is poor, laid messy, repair, safety distance is not enough, wire connectors, easy fever, basically not installed limi tation, half the total protection frequent action can't even put into operation. Farmers to regulate power consumption, and also to establish the necessary checks system, record system, responsibility system of guidance and management system, to use based on the facts and data to talk, and can't do with experience, these will work in the information management of synchronization.

      (3) electric safety consciousness, the equipment is serious damage. The rural security electricity publicity, use electricity safety consciousness, cause accident harm increased, theft, and external force damage, engineering construction damage electric power facilities and pull up, private abuse illegal buildings, cross power supply, who access backup power supply for the lamp violation behavior, threatening the safety of the rural equipment and personnel, and direct threat and influence powered security management.

      C use the information to rural power grid management of low pressure

      (1) use of carrier meter reading system to realize the remote computer automatic meter reading, the operator can be only half an hour of electricity tens of thousands a user crewmen copy it back to low, such not only saves time, and greatly liberating the productive forces.

      (2) reduce additional line loss. Additional line loss mainly from plan for Aaron card round the electric meter don't walk by words, people move round, short circuit TouDian degree program. To realize the remote automatic meter reading, plan degrees don't go round the word, not the computer still in count, so copy of data is accurate. User TouDian problem, we can through the change every day to Taiwan total electricity supply, line loss situation, the residents of each user table of the historical record of the electricity supply out, the surveillance.

      (3) the biggest load of sampling, the computer can realize the artificial cannot achieve the maximum load of sampling, such not only can the data in the table scroll, at the same time for the maximum load, sampling is very accurate to give the curve were also is very reliable.

      (4) use remote automatic meter reading system can also very easy according to the historical data of every day three phases balance realize accurate analysis.

      D summary

      To sum up, the use of rural informatization of low voltage power grid management, such not only can solve the problems left over by some in the countryside, and can greatly save manpower and material resources. At the same time use the principle, but also through the telephone line to half for units collection of users YongDianShu, combined with the traditional meter reading way, every month to one half of the electricity supply timely analysis, more and more detailed and accurate information. And low cost of users meter reading device type farmers power consumption are necessary, this method not only solved the problem of NongDianGong repeated operation, also solve the preliminary examination, and improve the accuracy of the problem.
