摘要：目前大型礦場(chǎng)使用的提升裝置存在控制精度低、調(diào)速性能不佳、電能消耗較大等明顯缺點(diǎn)。采用基于變頻調(diào)速控制方法協(xié)同超級(jí)電容儲(chǔ)能技術(shù)，開展提升裝置電氣系統(tǒng)的節(jié)能設(shè)計(jì)，在改善提升裝置的控制精度和調(diào)速性能的同時(shí)，采用超級(jí)電容儲(chǔ)能技術(shù)回收儲(chǔ)存電機(jī)制動(dòng)電能；在特殊情況下，釋放超級(jí)電容儲(chǔ)存電能，為系統(tǒng)正常運(yùn)行提供電力保障。結(jié)果表明，提升裝置調(diào)速工況時(shí)控制精度得到明顯改善，系統(tǒng)調(diào)速性能良好，超級(jí)電容儲(chǔ)能可實(shí)現(xiàn)對(duì)制動(dòng)電能的存儲(chǔ)與合理應(yīng)用，滿足系統(tǒng)節(jié)能要求。

Abstract: The lifting device used in large mines has some obvious disadvantages of low control accuracy, poor timing performance and large power consumption. To solve these problems, the paper combines frequency control method with super-capacitor energy storage technology to improve the energy-saving of electrical system of the lifting device. With the adoption of super-capacitor energy storage technology,this design can recover and store the electric energy from the motor braking while improving control accuracy and timing performance. In some special cases, the power stored by the super-capacitor is also released to ensure the normal running of the system. The results show that the improved design of the lifting device not only increases control accuracy and timing performance under frequency control condition, but also realizes the storage and reasonable application of braking energy to meet the energy-saving requirement of the system through using the super-capacitor.

Key words: lifting device; frequency control; energy recovery; super-capacitor; vector control
