Abstract
Power network monitoring systems are presented. In some embodiments, the system includes a master device installed in at least one substation among the plurality of substations, and slave devices installed in remaining substations except from the substation in which the master device is installed. Each of the slave devices may include a first PMU configured to measure data such as reactive/active power, magnitudes and phase angles of a voltage and current of the substation in which the slave device is installed. The master device may analyze data transmitted from each of the slave devices, may generate a command for taking action of a corresponding slave device based on an analyzed result, and may transmit the generated command to the corresponding slave device.
Claims19
A power network monitoring system that monitors a plurality of substations, the power network monitoring system comprising:
- a master device configured to be installed in at least one substation among a plurality of substations;
- and
- a plurality of slave devices configured to be installed in the plurality of substations except from the substation in which the master device is installed,
- wherein each of the slave devices comprises:
- a first phasor measurement unit (PMU) configured to measure data of the substation in which the slave device is installed;
- and
- a first communication unit configured to transmit the data measured by the first PMU to the master device,
- wherein the master device is configured to analyze the data transmitted from each of the slave devices, generate a command for taking action of a corresponding slave device based on the analyzed data, and transmit the generated command to the corresponding slave device.
A method of monitoring a power network monitoring system which comprises a master device configured to be installed in at least one of a plurality of substations that are connected to each other, and a plurality of slave devices configured to be installed in remaining substations except from the substation in which the master device is installed, the method comprising:
- receiving data from one of a plurality of slave devices;
- checking whether the received data is AC system data;
- analyzing the received data with reference to an AC system, when the received data is the AC system data;
- generating a command for taking an action of a corresponding slave device based on the analyzed data;
- and
- transmitting the generated command to the corresponding slave device.
