摘要
针对当前火电厂凝结水泵高压变频改造现状,从"电气改造方案"、"保护功能"、"控制策略"三个方面,阐述了改造应注意的问题。并以广安电厂600 MW机组凝结水泵高压变频改造为例,论证了注意这三方面问题的必要性和可行性。
Aiming at the current reforming situation of high-voltage frequency conversion of condensate pump in thermal power plants,as viewed from the electrical reforming scheme,protection function and control strategy,the problems needing attention in the reforming are described.Taking high-voltage frequency conversion reforming of condensate pump of 600 MW units in Guang'an Power Plant for example,the necessity and feasibility of the above-mentioned three aspects are demonstrated.
