Humen Town, With Power Supply Reliability Planning

Power system reliability depends on the system equipment and the operating cond itions, the reliability of the main research equipment itself, the system combined equip ment reliability, system reliability and system reliability and customer service reliability coordination and cooperation. Distribution grid distribution network transformation to achieve the elimination of weak links, optimizing the distribution network structure an d improve the distribution network supply capacity, adaptability and automation level, and gradually realize the standardization and facilities DISTRIBUTION NETWORK C ONNECTION standardization objectives. Distribution network construction should follo w the "safe, reliable, reasonable structure, advanced technology, environmental protectio n, energy conservation and standardized and unified" principle. Distribution network te chnical equipment must proceed from reality, combined with regional characteristics, ac tively and steadily adopting new technologies, new materials, new processes, should ac tively adopt energy conservation, energy, environmental protection, maintenance or less to maintain the advanced technologies and products.Different levels of the city and different categories of supply areas should be diff erent construction standards. Dongguan Power Supply Bureau reliability based plannin g objectives and requirements of the development of power grid construction, launche d the " Dongguan Power Supply Reliability Plan" research projects. Project team wit h the current distribution network Humen Town, Dongguan operating characteristics an d problems, developed a distribution network in Dongguan Power Supply Bureau reli ability goals planning.The project in Dongguan Power Supply Bureau Reliability Analysis based on sup ply reliability indicators proposed decomposition uniform principles and calculation mo del; combines reliability assessment techniques and optimization theory, Dongguan Po wer Supply Bureau reliability improvement measures. By improving the cost-effectiven ess analysis, to obtain a unified reliability and economy, which may be of Dongguan Power Supply Bureau and reliability of electric power engineering project managemen t to enhance provide a useful reference, has important practical engineering significan ce.Innovative research is reflected in(A) the reliability index of the grass-roots units actual usage of the calendar ye ar, the annual project, grid levels, reliability, management and other factors into ac count to the reliability index decomposition model(2) assess the reliability of the model proposed for the first time took into acc ount the capacity of the main network, substation wiring forms, different ring forms, switching capacity, overhead lines with poles and other factors, may reflect the Dongguan area distribution network reliability level(3) for the various improvement measures feasibility analysis, the application o f cost-benefit analysis of the measures in accordance with the principles to improve th e reliability level of funding units use to sort the reliability of the planning objectives as constraints, the order proposed reform measures by year embodiment...
