[0002] "Research on Elevator Energy-Saving Technology Based on Supercapacitors" (Zhou Jichao, December 2016) provides a method for energy-saving control of elevators based on supercapacitors. This method can achieve 4 % energy-saving efficiency. However, in actual production, industrial elevators use higher-power motors due to load requirements and redundant design requirements. The parameter dispersion of capacitors makes it difficult to simply homogenize the control scheme of a single supercapacitor in the scheme of multi-channel supercapacitors, and there will be differences in electrical performance between multi-channel supercapacitors based on the dispersion of supercapacitor parameters. At present, the existing technology There is no optimization method for the cooperative control of multi-channel supercapacitors

Abstract

The invention provides a supercapacitor-based industrial lift energy-saving control adjustment method comprising the forward testing process and the feedback adjustment process. The forward testing process comprises the following steps of (1) obtaining of parameter values, (2) outputting of the adjustment values and (3) output control. The feedback adjustment process comprises the following stepsof (1) obtaining of a feedback value, (2) reverse calculation and (3) parameter adjustment. Through the mode of the two stages of the forward testing process and the feedback adjustment process, control parameters can be optimized dynamically specific to actual electrical performance of multichannel supercapacitors, thus cooperative control of the multichannel supercapacitors is greatly optimized,and in addition, an algorithm self-optimization mode is adopted, so that experiment cost brought by a large number of multichannel supercapacitor cooperative control experiments is avoided.

Description

technical field [0001] The invention relates to an energy-saving control and adjustment method for an industrial elevator based on a supercapacitor. Background technique [0002] "Research on Elevator Energy-Saving Technology Based on Supercapacitors" (Zhou Jichao, December 2016) provides a method for energy-saving control of elevators based on supercapacitors. This method can achieve 4 % energy-saving efficiency, however, in actual production, industrial elevators use higher-power motors due to load requirements and redundant design requirements. The parameter dispersion of capacitors makes it difficult to simply homogenize the control scheme of single-channel supercapacitors in the scheme of multi-channel supercapacitors, and there will be differences in electrical performance between multi-channel supercapacitors based on the dispersion of supercapacitor parameters. Currently, the existing technology There is no optimization method for the cooperative control of multi-ch...
