It is hard to measure the level correctly. So it brings some difficulties to the control based on the drum water level, even the alarm. Usually, more than three water gauges are installed for drum water level measurement. And it adopts twooutofthree strategy for obtaining the final alarm signal in distributed control system (DCS), which is often the false alarm. Without the right alarm, it is to result in very serious disaster on power plant. One approach based on BackPropagation (BP) Neural Network is proposed in this paper for solving the problem. The measurements from different water gauges are inputted into the BP Neural Network after fuzzy process and the output of the Network represents the type of alarm. Some data of the drum water level from a nuclear power plant is applied with the method of the paper. From the experiments, it can be seen that the alarm accuracy is increased rapidly.Keywords:drum water level。DCS。 BP Neural Network。 alarm。 nuclear power plantDrum water level is an important parameter for boilers, especially for highrunning condition and highcapacity boilers, to run safely during production in thermal power plants. It is very important to monitor the drum level accurately at all times. Drum level may change frequently because of changes in load, busting conditions and water supply.Based on this control system, the dry of boiler and the failure of water screen tube can be prevented. Besides, the system must be able to unfold the purge valve—or stop the boiler if necessary ——automatically when the boiler is full so as to avoid unexpected accidents and expansion of accidents . There are several different water gages
