ABOUT COMPANY SOLUTIONS Газоперекачивающие компрессорные станции Теплоэлектростанции Атомные электростанции Гидроэлектростанции Автоматизация объектов энергетики Информационно-поисковая система Испытательные полигоны Автоматизированные системы пожарообнаружения Учет энергоресурсов (АСКУЭР) PARTNERS CONTACTS CONTROLLERS CATALOG VACANCIES ACS TP AVO GAS The gas air cooler (hereinafter AVO) provides gas cooling at the compressor outlet to the temperatures required by the technology. The central controller in the control cabinet collects data from temperature sensors t1-t16, compares it with the operating modes of the motors, with their parameters (frequency, residual resource, control prohibition) selects the optimal operating mode from the point of view of energy efficiency. Control actions are sent to the VFD to form a control action on the electric motor, as well as to the operator's workstation screen to control the technical process. All processes occurring in the ACS, as well as the data collected by the system about the modes and parameters of the AVO operation, are recorded in the archive on the ACS AVO server. An optional system for diagnostics of engines by electrical parameters is provided, which allows using non-destructive testing methods to assess the technical condition of the equipment (see diagnostics). Control and regulation functions: turning on / off fans at the command of the dispatcher; automatic regulation of the gas temperature at the AVO outlet; maintaining the set temperature at the AVO outlet; measurement and display of the total gas temperature at the gas AVO outlet; measurement and display of the gas temperature at the outlet of each of the 16 sections of the gas AVO; measurement of ambient air temperature; software, sequential smooth start of a group of electric motors while simultaneously turning them on. Informational functions: collection and processing of analog technological parameters; collection and processing of discrete parameters characterizing the state and position of actuators; information exchange with the dispatcher's workstation via a digital communication channel; exchange of information via the RS-485 interface with intelligent ShU equipment (VFD, switches). presentation of AVO mnemonic diagrams on the screen of the operator's workstation with indication of the measured parameters in the places of control and the positions of the executive mechanisms; creation and storage in non-volatile memory of an electronic "event log" for failures and operating time of each electric motor. Secondary functions: accounting of equipment operating time; ensuring uniform development of the resource by all electric motors by turning on the fans according to the programmed cycle of "resource saving", as well as according to the schedule set by the technological regulations. diagnostics of the state of technical means of control, including the serviceability of measuring and executive channels; verification of the reliability of information signals. The system is built in such a way that the shutdown of higher levels does not affect the operation of the local level of the ACS. Disconnection of the local controller, in turn, does not entail a shutdown of the AVO - the fans continue to operate in the modes preceding the shutdown. Site Map Letter © 1992–2015.
