Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a comprehensive energy efficiency evaluation method and system based on a distribution station area. Background technique [0002] The distribution station area is oriented to the majority of users and is the basic unit to ensure the quality of the power supply terminal and the realization of the terminal. It is connected to the main grid frame of the power grid and connected to thousands of households. It is related to safe production and power grid operation internally, and affects high-quality services and brands externally. Image is an important foundation for the development of power supply enterprises. While the "quality and quantity" of the distribution network have been comprehensively and rapidly improved, there are still individual differences between different regions, which are quite prominent in some regions. For this reason, establishing a scientific and reason...

Problems solved by technology

[0003] The traditional distribution network evaluation system mainly evaluates the operation reliability of the power grid, the power quality at the end of the power user, the safety of power operation, and the construction scale of the distribution network project. not strong meaning

For example, some distribution network evaluations only establish evaluation indicators for distribution network equipment utilization, mainly considering different load states of transformers and power supply lines, and do not involve static indicators reflecting equipment parameters; some distribution network evaluations are based on According to the division and evaluation of voltage levels, an index system has been established for different voltage levels of distribution networks, but the division according to voltage levels ignores the differences in distribution network structure and load density in various regions, and is not comparable; in addition, there is a distribution network Power grid evaluation system, the distribution network indicators established by it are all dynamic operation indicators, without considering the impact of static indicators on the energy efficiency of distribution network, and the consistency analysis of the established judgment matrix is ​​not done, which reduces the objectiveness of the evaluation results and some have only established energy efficiency evaluation models for power users, not involving distribution network energy efficiency evaluation models; or put forward comprehensive evaluation index systems and methods for distribution network planning, although some energy efficiency indicators are involved, but not comprehensive enough
