An Online Core Power Distribution Monitoring System

Abstract

An on-line core power distribution monitoring system belongs to the technical field of nuclear power plant core monitoring. The system includes a first monitoring server, a second monitoring server, a prediction server, a first isolation device, a second isolation device, a mirror server, and a client terminal; the first monitoring server and the second monitoring server are used for real-time monitoring of the core For power distribution, the monitoring data is transmitted to the prediction server through the first isolation device; the prediction server transmits the monitoring data to the mirror server through the second isolation device; the mirror server communicates bidirectionally with the client terminal through a firewall. On the basis of not changing the design of the original industrial network, the invention utilizes the new network architecture to realize the isolation between the industrial network of the nuclear power plant and the administrative office network, has little influence, less construction, low cost, and can ensure real-time monitoring.

Description

technical field [0001] The invention belongs to the technical field of on-line core power monitoring, and in particular relates to an on-line core power distribution monitoring system, which is used for the network architecture of the third-generation nuclear power plant administrative office network accessing OCPDMS. Background technique [0002] Third-generation nuclear power plants are generally equipped with OCPDMS. The system is used for real-time monitoring of the three-dimensional core power distribution of nuclear power plant reactors, and also provides core prediction and calculation functions. The system includes 3 servers: 2 monitoring servers and 1 prediction server, among which 2 monitoring servers are used to provide redundant real-time core power distribution monitoring, and 1 prediction server can be used for users to perform core prediction calculations. An essential tool for a reactive management plan. [0003] According to the original design, the monito...

Problems solved by technology

The one-way isolation device used in the original design has not been tested and certified by the designated department of the state, so the forecast server still needs to be used as equipment in the production control area, and the forecast server and the administrative office network are only separated by a firewall, which does not meet the safety requirements of the power monitoring system Require

In order to meet the safety protection regulations of the power monitoring system, it is considered to replace the original one-way isolating device with a domestic one-way isolating device that meets the regulations. However, due to the different structure of the isolating device, there are compatibility problems in data transmission, which will affect the data transmission of other users; if for To transmit data smoothly, it is necessary to change the original design of the power plant, which involves the transformation or redesign of the industrial control network, and the transformation project is large and time-consuming.

If a domestic compliant one-way isolation device is added between the administrative office network and the forecasting server, it will not be able to meet the actual demand for two-way communication between the forecasting server and the administrative office network
