A Model-Based Operator Assisted Computing System

Abstract

The invention provides a model-based operator auxiliary computing system. The model-based operator auxiliary computing system comprises a client side, a server side and an engineer station, wherein the client side and the server side are respectively connected with a power plant instrument control system network, and the engineer station is used for configuring data points. The client side comprises a plurality of operation stations which are connected with the power plant instrument control system network. The server side comprises a first interface server and a second interface server, and the first interface server and the second interface server are connected with the power plant instrument control system network and are in redundancy configuration. A main server is connected with the first interface server and the second interface server respectively, and a standby server is connected with the first interface server and the second interface server respectively. The main server is further connected with a main server displayer, and the standby server is further connected with a standby server displayer. The engineer station comprises a plurality of engineer stations which are connected with the power plant instrument control system network. By means of the model-based operator auxiliary computing system, the calculated loads of operators can be lightened, human errors are avoided, the overall safety of a nuclear power plant is improved, and meanwhile the operators can be better supported to achieve the operation of the power plant.

Description

technical field [0001] The invention relates to a digital instrument control system of a nuclear power plant, in particular to a model-based operator-assisted computing system. Background technique [0002] With the continuous development of the digital I&C system of nuclear power plants, the amount of information in the I&C network of nuclear power plants is also increasing. In order to help the operator obtain the key information for monitoring and operating the power plant, it is necessary to use the information in the I&C network to calculate the key information required by the operator, so as to better support the operator to grasp the current state of the power plant. In NPPs currently in service, these calculations are generally done in the following ways: [0003] (1) Manual calculation by the operator, such as the countdown rate calculation of Qinshan Phase I NPP, etc. [0004] (2) The controller calculation of the instrument control system, such as the time avera...

Problems solved by technology

[0006] Obviously, there are obvious defects in the above three methods of calculation: the operator can only complete simple calculations manually, and at the same time it will increase his mental load, and it is also prone to human error, which poses a potential threat to the safety of the power plant; The controller calculation of the instrument control system will occupy the resources of the controller and affect the performance of the instrument control system; the calculation of multiple small calculation software also has calculation programs that are too scattered, which is not convenient for the management and maintenance of calculation programs

In addition, using controller calculations and small software calculations, after the program is designed, it can only be modified by professional software developers, and it is difficult for users to carry out secondary development of existing application services according to new needs.
