Key words: electrical automation power plant
electrical power plant automation system applications 1) automatic meter reading function. Measurement and control devices using their own function or transfer meter pulse signal, in the main station to generate electricity on-line statistical reports enables a dedicated auxiliary power meter reading capability of the system. 2) The generator run status monitoring,Beats By Dre Headphones, real-time visual display generator running state diagram for the generator running to provide guidance. 3) electrical equipment management, including protection and automatic devices of accounting,radii shoes sale, file maintenance records. 4) The value management, value changes of distance and online auto efficiency core. Future electrical system master can also be extended to visual computing and power plant protection setting value management system. 5) The failure information management. 6) electric motor fault diagnosis and condition-based maintenance. Waveform when the motor starts by the analysis of squirrel cage broken bars, etc. can malfunction.
specific operation 1, the background layer dual station control operator workstation redundancy, complete the entire plant electrical equipment monitoring, control, reporting, and all monitoring functions. Configure a station engineer to complete the system maintenance, fault recording analysis, protection and management functions, and cater to operation ticket expert system workstations. Configuration of a UT-2000 integrated operating panel, with five anti-mimic, the signal return to screen, smart handheld screen one of the three-screen function for the operating personnel to provide more intuitive, more reliable way of monitoring. 2, the spacing layer spacing layer device in accordance with different characteristics and requirements can be divided into network control subsystem, the subsystem unit, Plant subsystems,Oakley sunglasses sale, subsystems over the same period, five anti-subsystem, subsystem, and several other parts of remote viewing. Interval layer uses the RS485, Ethernet communications can be applied. Interval level measurement and control devices to protect both focus group screen, you can also spread switch installed in the cabinet. Distributed through the communication cable installation to connect with the main control room, save a large number of secondary control cables.
network control subsystem, 1) high-pressure outlet, 66kV voltage level above the line used to protect and separate the configuration and control, configuration UT-600 Series protection and UT-600 series monitoring and control devices. Such as the 110kV line using UT-611 high-voltage lines. Protection and UT-641 integrated measurement and control devices. 2) low-pressure outlet, 35kV and below the line voltage using UT-99 Series protection and control integration devices, such as UT-9911 circuit protection and control devices sub-units, generators, generators need to improve protection. Configuration UT-9991 generator differential protection UT-9992 generator back-up protection and control devices,diesel store paris, UT-9993 generator rotor earth fault protection device, for small and medium-capacity generators to provide complete protection, and communication with the unit and the circuit measurement control functions. Generator speed, voltage regulator and excitation parameters collected by the UT-641 features such as integrated monitoring and control devices to complete, UT-64 allows AC and DC measurement, signal acquisition and remote control functions. Centralized control unit configuration UT-ZHXH command signal devices, mechanical and electrical contact. 2) The transformer unit. The use of transformer unit wiring unit, configure the UT-9931-transformer unit differential protection UT-9992 generator back-up protection and control unit, UT-9993 generator rotor earth fault protection unit, UT-9934 non-power transformer protection devices. Configuration UT-641, complete unit speed, voltage regulator and excitation data acquisition functions.
