Method for judging running state of unit based on active power, rotating speed and starting rotating speed

The invention provides a method for judging the running state of the unit based on the active power, the rotating speed and the starting rotating speed, the running state of the fan can be monitored in real time according to the data transmitted by the fan PLC, and the loss which is not processed in time after the fan is shut down can be effectively reduced. The method comprises the following steps: a, collecting fan data, establishing communication with a fan master control PLC (Programmable Logic Controller), and storing the data transmitted by the PLC in a database; b, judging the running state of the fan according to the active power, the rotating speed and the starting rotating speed provided by a manufacturer; and c, informing maintenance personnel of the shutdown condition of the fan to overhaul, inspect and maintain the fan. 本发明提供了基于有功功率、转速、启动转速判断机组运行状态的方法，其能够根据风机PLC传输的数据对风机的运行状态进行实时的监测，可以有效的降低风机停机后未及时处理的损失。其包括：a采集风机数据、并与风机主控PLC建立通讯，将PLC传出的数据保存在数据库中；b通过有功功率、转速以及厂家提供的启动转速判断出风机运行状态；c将风机停机的情况告知维护人员对风机检修检
