Abstract Modern electronics systems consist of not only with the power electronics converters, but also with the friendly user interface which allow you to read the operating parameters and change them. The simplest solution of the user interface is to use alphanumeric display which displays information about the state of the converter. With a few additional buttons you can change the settings. This solution is simple, inexpensive but allows only local control (within walking distance from the system) and the number of displayed information is low. You can create extensive menu, but it causes problems with access to information. This paper presents the example of a rotating energy storage universal solution which is lack of the above mentioned disadvantages

The exhaust gas produced by the diesel engine is reclaimed to the mixing chamber where it was mixed with pure oxygen and argon. The mixture which forms "artificial air" will be used as the diesel intake to achieve the diesel engine’s working in closed cycle. The most critical part in closed cycle diesel engine control system is to control the oxygen concentration and specific heat of the intake. This paper is based on the design of GE9030-based PLC and the monitoring interface used in this paper is designed by KingView6.53, finally, the control of specific heat of the intake, concentration of the oxygen intake and pressure of the intake are realized. Moreover, real-time displaying, gathering and fault alarm of the operating parameters in this system are achieved.

Abstract A key function for a control system in a gas turbine train is to keep the operation of all components within a range of parameters that keep the unit safe. If the operating parameters of components fall outside the desired range for safe operation, the control system will detect these and create an alarm. For critical parameters, the control system may initiate an alarm and a shutdown of the unit. In many instances, an alarm may precede the shutdown command. Frequent discussions evolve around situations that lead to a shutdown of the train, as shutdowns impact the availability of the turbomachinery equipment, but in a wider sense also the availability of the compressor station. Therefore, shutdowns impact the profitability of a system. On the other hand, shutdowns may prevent significant, costly damage to the equipment, with significant downtime, and financial implications. In this lecture, we will discuss different methodologies for shutdown requirements, in the effort to maximize availability of units. Particular emphasis will be given to aging machines as well as machines where the instrumentation, and the control algorithms may no longer be state of the art, or where unnecessary or spurious shutdowns plague an installation.

New switching power supply gradually replaced the traditional linear power supply, but rarely has the operational status monitoring function. The design includes the main power supply and monitoring circuit design. The main circuit topology of the power supply is flyback DC-DC conversion body. The selection of the control circuit is current-controlled PWM chip. The monitoring circuit includes the design of detection and display circuit. The voltage and the current are detected respectively with the aid of the resistive subdivision in the testing circuit. The display circuit adopts PIC for sampling signal processing, and the dot matrix LCD12864 is used to display this power operating parameters. The power supply control system is simulated in Saber and Proteus software which monitors and observes the various parts of the circuit voltage and the output waveform. Finally, the hardware circuit is built and tested to prove the designed digital intelligent power feasibility.

Recent upgrading of the Facility for Modification and Analysis of Materials with Ion Beams (FAMA), in the Laboratory of Physics of the Vinca Institute of Nuclear Sciences, included modernization of its electron cyclotron resonance (ECR) ion source. The ECR ion source was extensively used for production of multiply charged ions from gases and solid substances for more than 15 years, during which time its major subsystems were expended and therefore, it required complete reconstruction. As a part of this reconstruction we designed and put together a completely new control system of the ECR ion source. It is a distributed and fiber-optically linked control system based on the Group3 Control hardware and the control application written in the Wonderware?s In Touch software. The control system should help and assist an operator in obtaining the appropriate operating parameters of the ECR ion source, maintaining and controlling operating parameters of the machine during its operation, as well as in monitoring weather the safety conditions are fulfilled during the operation of the machine. We tested the operation and performances of the new control system during the commissioning of the upgraded ECR ion source. Compared to the old one, the new system is more reliable, more userfriendly oriented, and it comprises several new useful control applications.
