Based on AggreGate SCADA/HMI the distributed system of data collection of the research nuclear reactor is created

Project Description

Long time the area of researches in nuclear physics of Russia was in search of permanent powerful neutron sources. The nuclear reactor with a big density of a neutron flow constructed at the St. Petersburg institute of nuclear physics of B.P. Konstantinov (which became a part of Kurchatov Institute recently), solved this problem by means of generation of the neutron flows of high density suitable for a broad spectrum of scientific experiments. According to the project of development, ensuring the centralized control of all complex of the reactor, required implementation of its observation using a single system of data collection and monitoring. Requirements to the SCADA system integrated in themselves collecting, storage and visualization of values of 11000 channels of input-output measured in hertz. Also possible increase in channels of input-output to 15000 was considered.

Solution

The special project selected AggreGate SCADA/HMI as main system of management of a complex of the reactor, all accompanying systems and processes. AggreGate also had an opportunity to perform monitoring of the equipment in all territory of a research institute. The staff of the Russian office of National Instruments company developed new AggreGate the driver for data acquisition in real time from the special controllers working on the NI-RT operating system. The driver uses the JSON protocol for data exchange with the controller's chassis that provides incredibly high rate of transmission quality of data (more than 150,000 values of tags per second). All received values go to special storage for storage of history of data. The failsafe architecture of AggreGate includes 4 pairs of the SCADA servers and database servers. These pairs work independently, providing high system availability and receiving a set of copies of all historical data.

Based on AggreGate SCADA/HMI the distributed system of data collection of the research nuclear reactor is created

More than 50 specially created human-computer interfaces (HMIs) perform observation of all processes and systems, including the heat-generating assembly, the reflector of a fissile region of the reactor, cooling circuits and a hitch of the reactor, pressure monitoring, cooling (including abnormal), cleaning of water and compressed air, turnover water supply, a radiation situation, the nitric equipment and the special sewerage. Other types of HMI visualize a status of technology and neutron processes of the reactor. The customized browser system of trends excellently compares values of metrics with their time marks, providing comprehensive monitoring of thousands of parameters in real time. It also allows to select a set of parameters for comparison of their trends from one chart. All controllers and the AggreGate servers synchronize the real time clock with Stratum-1 servers by means of the SNTP protocol.

All database servers and SCADA/HMI work on the operating system of ALT Linux Centaurus certified by Federal Service for Technical and Export Control of Russia.

The reached advantages

The AggreGate SCADA/HMI system provided umbrella control and monitoring of all processes and the systems of a complex of the nuclear reactor, having simplified management of a set of systems using a uniform control panel. Incredibly high capacity and cheryrekhuzlovy a failover cluster require existence of several powerful servers. However, the AggreGate settings were optimized for reduction of the most part of transactions of input-output of the database during normal system operation that made possible use of 12-core HP servers from only 16 GB of the RAM as basic nodes of a cluster of SCADA
