Patent ID: 8169106

Claim:
An Energy Management System (EMS) for controlling operation of a power generating facility connected to channels in optimum condition according to information regarding an entire power supply system received from a supervisory control and data acquisition (SCADA) system centralizing control of at least one remote terminal unit (RTU) installed at a remote area, the EMS comprising: a communication module for receiving channel information regarding a high voltage direct current (HVDC) system via a network; a circuit realization unit for generating an electric circuit representation of the HVDC system based on the received channel information, the generated electric circuit representation comprising a plurality of symbols, each of the plurality of symbols representing one of a plurality of constituent electric elements of the HVDC system, and connection information comprising one or more connective lines located between the plurality of symbols and indicating one or more electrical connections between the plurality of constituent electric elements; a system analyzing unit for determining an operation mode of the HVDC system based on the connection information of the generated electric circuit representation of the HVDC system; and a controller for managing and controlling the HVDC system by providing an energy management command in response to the determined operation mode, wherein the plurality of constituent electric elements include at least a transformer, an inverter, a converter or a circuit breaker.
