Stydying And Discussion On Charge Transfer On Power On Chancheng,Foshan

As Chancheng district is the political and cultural center of Foshan, customers are increasingly high demand for power supply reliability, Short no power failure can not meet the high requirements of customers, Power supply will become a major trend in Chancheng city to power supply, The improvement of power supply reliability in Foshan city is of great significance.The current domestic distribution network, including the Foshan Power Supply Bureau of the overhead line of the more intensive areas have a close loop power supply,And the development of technology is more mature,But the technology is mainly used in the overhead line. The use of a nuclear technology,And the city of Chancheng Foshan city district power supply 10 k V cable rate of 95%,Can not adopt a nuclear phase to carry out the work of charged ring,The study of the two nuclear phase technology is the key to the promotion of the work in the city. In this paper, the working data of the Chancheng Foshan Power Supply Bureau in the city are analyzed and sorted out by the data of the Power Supply Bureau,The characteristics of distribution network in Chancheng Foshan are summarized,The cable rate of Chancheng city in Foshan city is 95%, the ring network rate is 100% and the characteristics of the hand in hand type distribution network,For the following research directions:1、The relevant regulations and requirements for the operation of the power supply operation of the hand in hand are put forward. A model of the steady state current and impact current of the composite ring is established.2、 The factors affecting the current of the ring are analyzed. An effective method to reduce the loop current is proposed. Methods for the successful implementation of the pilot phase in the 10 kV cable line,Methods for the successful implementation of the pilot phase in the 10 kV cable line。3、The feasibility scheme of improving the condition of charged ring is proposed. Analysis and Research on the success of the charging and power supply reliability data of the pilot phase,Several factors that can not satisfy the condition of charged ring,In addition to the conventional nuclear phase and the two nuclear phase method,The two nuclear phase method of generating the parent stock, standby cabinet and the solution of the ring in the work,The factors that do not meet Charge transfer load are improved and the distribution of the distribution network is optimized. Feasibility study and analysis of several major schemes,Research on the application of the current technology to the future distribution network architecture,The feasible conditions of meeting Charge transfer load in Foshan city are summarized. Further discussion on the "N-1" connection mode for the future planning of Foshan distribution network,The conditions and requirements of Charge transfer load in the future are presented,The theory basis and the instruction significance for the 10 kV distribution network operation。...
