Background & Objective: Wireless networks are making its way for use in industrial control system applications. The installation of Wireless networks naturally provides a reduction in cable and its maintenance related costs, provides increased flexibility and mobility to enhance the performance of industrial control system. Method: This paper attempts to show the suitability of a wireless network in control system application of ECRH system at IIGTF. IEEE 802.11n network is implemented to interface field instruments with PLC based control system in an industry like environment. The two case studies with different control architecture are implemented with satisfactory test results. The first case demonstrates the use of a wireless network for monitoring and data acquisition of cooling water process parameters. The second case implements the control and monitoring of the DC power supply over the wireless network through a serial ASCII protocol. The performance of wireless communication alone in is evaluated using theoretical analysis, simulation and actual field measurement. Then overall performance of the case studies including field signals and PLC system is evaluated. Conclusion: The PLC application logic is developed for the implementation of logic functions to interface various field instruments and power supply. The DC power supply is simulated using Labview ™ for serial ASCII communication. The above said concept is proposed for the Local Control Unit being developed for ITER-India Test Gyrotron Facility.

Uninterruptible Power

The problem of development and implementation of a simple and effective method of the rectifiers operation control for the modular uninterruptible DC power supply unit in order to increase its reliability is considered in this paper. The main idea of the method is to control the process of cyclic shifting of the switched-on power modules of the uninterruptible power supply by series switching into operation of each subsequent module from their unloaded reserve and switching out the previous one. The paper presents the control system structure where in addition to the central control module, it is proposed to add the control unit for power modules, which is responsible for implementing the process of their switching on and monitors their condition. In order to investigate the effectiveness of the proposed method, computer simulation model describing the power modules control logic is developed. The Simulink visual modeling environment and the mathematical tools of the Stateflow library component using state and transition diagrams are used in order to develop the simulation model. The developed simulation model is tested and the simulation results are given in the form of time diagrams of state change. The іmplementation of the developed method, due to the uniform reduction of the period during which the power modules of the uninterruptible power supply are on the switched-on loaded state, makes it possible to increase their operating time to failure, which in turn increases its reliability without deteriorating energy efficiency. The simulation results demonstrate the efficiency of the developed algorithm in various system operation modes. Based on the proposed method, hardware and software which is implemented as a part of intelligent computerized control system for uninterruptible DC power supply is created.

This paper describes the high speed and the cost effective of the general purpose industrial control system named as Programmable controller for industrial automation (PCIA). It is a replacement of expensive controllers/ PLCs that are used in industries for automation purpose. PCIA is real-time power efficient and reliable controller with a facility of data acquisition and monitoring on its touch screen using interfacing module. This control system can automate any type of industrial machinery and processes. The core element of PCIA is programmable AVR (Advance Virtual RISC) microcontroller which controls each and every action of Programmable controller for industrial automation. It compromises of nine different modules CPU, HMI, digital input, digital output, analog input, analog output, thermocouple module and power supply modules. The software of PCIA is written in C language. Special circuitries are used in power supply and other modules are also used to protect the system from different industrial noises.
