Abstract Production of green electrical energy and green natural gas are the main goals of zero-carbon emission policy. Power to Gas plants (P2G) can be used to overcome difficulties with increase in intermittent renewable energy production, gas shortages and organic waste management. In this paper, a design, a model, and a control system for a Power to Gas plant is proposed. To achieve a high performance P2G plant, its design is based on biochar gasification and biological methanation processes. With the given mathematical models of electrolysis, gasification and methanation, calculation of needed feedstock and energy consumption as well as calculation of produced methane becomes easy obtainable. Proposed control system enables to precisely follow frequent operation change requests due to dynamical conditions in leaned electricity or gas grids. Simulation study of the automated plant operation using Matlab/Simulink has been done. This research gives all prerequisites for optimal sizing and planning of the P2G plant operation in dynamic technical and economic conditions.

Purpose This paper aims to propose a spreadsheet method for modeling and simulation of a retraction system mechanism for the retractable self-launching system for a high-performance glider. Design/methodology/approach More precisely, the method is based on parametric link design using Excel spreadsheets. Findings This method can be used for kinematic and dynamic analysis, graphical plotting and allows simulation of control kinematics with the ability to make quick and easy parametric changes to a design. It also has the ability to calculate the loads imposed on each component in the control system as a function of input loads and position. Practical implications This paper shows that it is possible to model complex control systems quickly and easily using spreadsheet programs already owned by most small companies. The spreadsheet model is a parametric model, and it gives a simple visual presentation of the control system with interactive movement and control by the user. Originality/value This spreadsheet model in conjunction with a simple CAD program enables the rapid and cost-effective development of control system components.

This passage mainly introduces about the design of liquid level and boundary measuring control at sewage re-flooding craft in small split oil field. In order to achieve automatically cutting flooding and re-flooding in the procedure in small split oil-field, the scheme is to test liquid level and boundary by using high performance to price ratio new double level gauge, to utilize electric valve instead of mechanical valve and to choose PLC to control system logic. Eventually, it will reduce the labor intensity.

Measurement And Control

For transient electromagnetic meter home-made, there are some disadvantages, for example early signal detection is difficulty, and speed and accuracy of signal acquisition is no high. Therefore a high-performance TEM based on embedded PC is designed to overcome these disadvantages. And its main part is measurement and control system, which design is mainly introduced. The system consists of a transmitter and receiver modules, which hardware block diagram and schematic design are introduced in detail. Laboratory tests for the system developed show that the electromagnetic transmitter module has advantages of short off-time and high transmitting current detection accuracy; the electromagnetic receiver has advantage of high sampling speed, big dynamic range and achieving accurate measurement of early signal. Laboratory test results are satisfactory.

Contrary to the problem that automobile switches have various kinds and large differences in the structure and performance so that traditional testing methods have been unable to meet the testing requirements of high performance switches, the paper designs a new detection system used to detect the functions of general auto switches which applies the developing environment LabVIEW based on virtual instrument technology and adopts the technology of embedded observe and control system. Using PC as the host computer, the system adopts the LabVIEW8.5 to compile a real-time monitoring system with good human-computer interface; S3C2440-ARM9 processor is used as the main controller of observe and control system in the inferior computer which collects output current signal when the circuit is conducted after switch is pressed. After the coding process of LwIP software protocol and the drive of Ethernet controller DM9000, the signal is transmitted to PC through Ethernet interface. Compared with conventional testing measures, this system greatly improves the real-time performance as well as working efficiency of detecting switch functions and reduces the corresponding human and material resources.
