DISTRIBUTION TYPE PARALLEL OPERATION CONTROL UNIT OF SHIP GENERATOR

摘要

PURPOSE: A distribution type parallel operation control unit of a ship generator is provided to control distributively a plurality of generators and prevent a trouble of a total system due to an error of a controller by using each controller corresponding to each generator. CONSTITUTION: A distribution type parallel operation control unit of a ship generator includes a plurality of distributive controllers and a display. The distributive controllers(200,300,400) are connected to a main bus in order to detect a frequency phase of the main bus. The distributive controllers are connected to plural generators in order to measure voltages, currents, and frequencies of the generators. In addition, the distributive controllers supply the electric energy of the generators to the load through the main bus by turning on an air circuit breaker when the phase of the main bus corresponds to the frequency phase of the generators. The display is connected to the distributive controller in order to display operating states and alarming states of the generators and perform particular functions.
