Embodiment Construction

[0007] The implementation process of this method is as shown in the accompanying drawing, at first carry out parameter selection; Then carry out sampling, in this example, the selected parameter is sampled by isolation amplifier; Then sampling data is sent into data acquisition system, and this data acquisition The system is a comprehensive system that integrates data processing, alarm, and data transmission functions; finally, the data acquisition system transmits the processed data to the PDS and the main control room, and the data acquisition system also stores the data, of which PDS is The heavy water reactor real-time monitoring system and the data acquisition system are connected to the PI on the LAN through the PDS.

[0008] The above PDS: plant display system (real-time monitoring system); PI: plant information system

Abstract

A digitalization-detecting method of nuclear power station with heavy water reactor includes selecting parameters, sampling, transmitting data to data collection system, transmitting data outputted from data collection system to master control room and simultaneously storing said data.

Description

technical field [0001] The invention belongs to the field of signal transmission and processing, and in particular relates to a digital monitoring method for a heavy water reactor nuclear power plant. Background technique [0002] The shutdown protection system is in the design of nuclear power plants. In order to comply with the public reference dose limits stipulated by the National Nuclear Safety Administration, according to different design basis accidents, select protection parameters and appropriate setting values, and control the insertion of shutdown rods / Injection of gadolinium nitrate poison into the protection system of the reactor core. The purpose is to shut down the reactor quickly enough in the event of an accident to quickly reduce the energy generated in the fuel, thereby protecting the safety of the reactor. The existing heavy water reactor shutdown protection system is mainly composed of two parts: control logic and data monitoring. The working process ...
