隨着我国社会经济不断发展,各界人士对生活供水泵房电机的变频改造和使用十分重视。在信息化时代背景下,能源消耗是企业发展必不可少的环节,而中国现如今正处于人口数量多、资源不足的状况。为了彻底实施政府节约资源方针,提高能源的利用率,需要对水泵房电机进行变频改造,实现节能与发展共同进行。根据有关人员调查发现,全国泵类电机耗电量已接近全国电力消耗的20%,其中水泵电机电力消耗最为严重。由于生产情况与用水时间具有不确定因素,导致出现能量消耗高、压力不稳定等问题,为了确保水池水量能保持平衡,通常工作人员会通过阀门控制水量平衡。这样长此以往,会增加工作人员负担,同时很难确保水压力的平衡[1]。

1.1 变频器工作原理
变频器是通过将电网电源整流后,再通过逆向流通变成频率,电压可变的交流电供应给相关电动机专用电源装置,主要是采用超大规模专用单片机、功率模块两个部门组成。……
