Abstract
The hydrogen isotopes separation plants have special requests related to safety operation and avoidance of radiological fluid leakage and explosion conditions. That involves monitoring and acquisition of the process parameters, complex parameter control, as well as specific calculation for each control loop from the plant, according to the process requirements (temperatures, flows, pressures).
The system developed and described in the present paper is based on a SCADA (Supervisory Control and Data Acquisition) platform which contains: network communication, PLCs (Programmable Logic Controller) and HMI (Human Machine Interface). The control of process parameters has been done using the functions from the embedded programmable code of the PLC’s which allows having independent or combinations of PID components: proportional/integrator/ derivative. Choosing the right control scheme and tuning PID loops corrects behavior of the system, improves the performance and leads to a safe operation of the LPCE process.
