目前,国内外变频空调压缩机大多采用内嵌式永磁同步电机,其控制难度主要有2点:一是应对不同电机厂家之间差异化的参数设计,二是应对国内外市场复杂的供电电源状况。本项目对影响永磁同步电机控制系统的内、外部参数分别进行了深入研究,有效解决了由电机参数差异及外部电源变化带来的空调整机问题,大幅提升了产品的能效与可靠性、降低了产品噪声。由于本项目所发明的多项关键技术填补了行业空白,直接形成多条企业产品卖点,实现海信空调2014~2015年新增产值140,097万元,新增利润16436万元,新增税收1895万元。另外,由于自适应控制的多项关键技术,大大降低市场维修成本,保守估计,每年节约维修成本200万元以上。本项目荣获“2015年山东省科技创新奖三等奖”。

Currently, air-conditioning frequency variable compressor mostly uses interior permanent magnet synchronous motor (PMSM), whose control difficulties are different parameters design in various motor factories and complicated power supply situation in domestic and foreign markets.

This project studies in depth the inner and outer parameters which have effects on PMSM control system, and effectively solves the problem caused by different motor parameters and outer power supply’s variation. Energy efficiency and reliability are dramatically improved with noises decreased.

A number of key technology inventions fill gaps of the field, forming multiple selling points. In 2014-2015, the company newly added output value of 1,400.97 million yuan, profits of 164.36 million yuan, taxes of 18.95 million yuan. Further, benefited from these achievements, market maintenance cost are highly reduced, with a conservative estimation of saving more than 2 million yuan annually.

This project wins the third prize of 2015 Shandong Province Science and Technology Innovation Award.
