IS200EPSMG2A IS200EPSMG2A IS200EPSMG2A electric dust removal, are not included in the DCS system for the time being. DCS control level and technical requirements for electrical system The whole process of automatic program control can be realized from boiler ignition to generator grid-connected initial load. (Of course, a limited number of breakpoints can be set…
IS200DTURH1A IS200DTURH1A IS200DTURH1A DCS monitoring. All the electrical systems in the main plant from the booster station (excluding the booster station) to the power plant side are included in the DCS monitoring. The main systems are summarized as follows: Generation group system (excluding the ventilation system of the transformer itself); Generator excitation system; High voltage…
IS200DTTCH1A IS200DTTCH1A IS200DTTCH1A operation. When some systems or equipment are in normal operation, they are often operated once for several months or longer. (2) The electrical equipment protection automatic device requires high reliability and fast operation speed. The protection speed of the development group should be within 40ms. Automatic quasi-synchronous voltage mode, speed, voltage adjustment…
IS200DTRTH1A IS200DTRTH1A IS200DTRTH1A 4917/5000 The thermal control of 300MW and above capacity units has been fully adopted DCS control system, gradually formed the data acquisition (DAS), analog control (MCS), sequential control (SCS), burner management (BMS) four systems. From the actual operation, DCS better realize its control function, and play the advantages of safety, economy, reliable…
IS200DTAIH1A IS200DTAIH1A IS200DTAIH1A modules is converted to a standard digital signal at the scene, just a cable can connect all the child standing, and then sends the field signal very briefly to the control room monitoring equipment, reduces the cost, It is also easy to install and maintain, and digital data transmission makes the system…
IS200DTCIH1A IS200DTCIH1A IS200DTCIH1A including the system configuration, database configuration, history library configuration, graphics configuration, control algorithm configuration, data report configuration, real-time data display, historical data, graphical display, parameter list, data printing, data input and parameter modification, control arithmetic, alarm processing, fault processing, communications control and man-machine interface and so on various aspects, And really realize…
IS200DSVOH1B IS200DSVOH1B IS200DSVOH1B mainly used in sensors, actuators, electrical drives, PLC, textile and building automation, etc. The latter two series adopt RS485 communication standards, with transmission rates ranging from 9.6kbps to 12Mbps, and transmission distances ranging from 1200M to l00m (depending on the transmission rate). The basic modes of media access control are token mode…
IS200DSPXH1D IS200DSPXH1D IS200DSPXH1D essential safety bus equipment. H2 is a high-speed bus with a transmission rate of 1Mbps (the transmission distance is 750m) or 2.5bps (the transmission distance is 500m). The number of nodes in each segment of H1 and H2 can reach 32, and the number can reach 240 after using repeater. Hl and…
IS200DSFCG1A IS200DSFCG1A IS200DSFCG1A influential fieldbuses have appeared in the past decade, such as Foundation fieldbus FF, Profibus, CAN, LONworks, HART and so on, and have been widely used. Only the first two fieldbuses are briefly described below. 3 Introduction to main fieldbuses \ 3.1 Foundation Fieldbus FF Foundation Fieldbus is a kind of fieldbus…
IS200DRLYH1A IS200DRLYH1A IS200DRLYH1A maintain the independent normal operation of the underlying equipment after it is disconnected from the upper level network, and its intelligence degree is greatly strengthened. 2.5 Highly intelligent field equipment Traditional DCS uses a relatively centralized control station, its control station is composed of CPU units and input/output units. Fieldbus control system…
