Abstract

The invention discloses a diesel generator model selection method and a diesel generator model selection device. The method comprises steps: as for each diesel generator candidate group, according to the net load of each time point in a set time length and the maximum power, the minimum power and the minimum operation time of each diesel generator in the diesel generator candidate group, the corresponding efficiency and the waste energy of the diesel generator candidate group and the average opening time of the diesel generators are determined; according to the determined frequency and the determined waste energy of each diesel generator candidate group and the average opening time of the diesel generators, the fraction value corresponding to each diesel generator candidate group is determined; a diesel generator candidate group with the highest fraction value is selected as a selected diesel generator group. Thus, the problems that the selected diesel generator group in the prior art is not high in operation efficiency, the diesel generator utilization rate is low, the waste energy is much, and resource waste and environmental pollution are caused are solved.

Description

technical field [0001] The invention relates to the technical field of equipment type selection, in particular to a type selection method and device for a diesel generator. Background technique [0002] With the continuous innovation of distributed power generation technology, the gradual exhaustion of conventional energy sources and the increasingly serious environmental pollution, countries all over the world are paying more and more attention to distributed power generation technology. Existing research and practice have shown that supplying distributed power generation functions in the form of microgrids is the most effective way to maximize the performance of distributed power generation energy supply systems. The so-called microgrid is a microgrid, which refers to a small power generation and distribution system composed of distributed power sources, energy conversion devices, related loads, monitoring and protection devices. It is an autonomous system capable of self-...
