Description
The REM 54_ rotating machine terminals (referred to as “machine terminals”further on) are designed to be used as the main protection system of generator andgenerator-transformer units in small and medium-power diesel, hydroelectric andsteam power plants, etc. The protection of large and/or important MV synchronousand asynchronous motors used e.g. in pumps,condition monitoring, general andcommunication functions within the scope of I/O connections, considering the totalCPU load. different kinds of applications.By means of the graphic HMI display, the control functions in the machine terminalindicate the status of disconnectors or circuit breakers locally. Further, the machineterminal allows status information from the circuit breakers and the disconnectors tobe transmitted to the remote control system. Controllable objects, such as CBs, canbe opened and closed over the remote control system. Status information and controlsignals are transmitted over the serial bus. Local control is also possible via the push-buttons on the front panel of the machine terminal.The protection functions of the machine terminals are designed for selective short-circuit and earth-fault protection of rotating machines. Further, unlike most otherpower system components, rotating machines also need protection against abnormaloperating conditions such as overcurrent, unbalanced load, overtemperature, over-and undervoltage, over- and underexcitation, over- and underfrequency andgenerator motoring. Also, underimpedance function is provided for line back-up.Furthermore, stall protection and cumulative start-up counter are provided for motorprotection start-up supervision.The machine terminals measure phase currents, phase-to-phase or phase-to-earthvoltages, neutral current, residual voltage, frequency and power factors. Active andreactive power is calculated from measured currents and voltages. Energy can becalculated on the basis of the measured power. The measured values can beindicated locally and remotely as scaled primary values.In addition to protection, measurement, control, condition monitoring and generalfunctions, the machine terminals are provided with a large amount of PLC functionsallowing several automation and sequence logic functions needed for substationautomation to be integrated into one unit. The data communication propertiesinclude SPA bus, Modbus or LON bus communication with higher-level equipment.Further, LON communication, together with PLC functions, minimizes the need forhardwiring between the machine terminals
