Description

System and method of remote error recovery for fault prevention of power SCADA}

The present invention relates to a remote failure recovery system and method for preventing power failure of a power Skada through unmanned operation of a substation through monitoring and control. In particular, the present invention relates to a DNP between a feed station and a remote device in a Skada management center. Skada for power that wants to contribute to the stable and reliable operation of Skada by conducting comparative verification of data and preventing the failure in advance through overall simulation test of the feeder's master, FEP, communication line, and remote device. The present invention relates to a remote failover system and a method for preventing a failure.

Skada is an industrial automation system that detects the status information of a large number of remote power equipments in remote areas and transmits them to a power distribution center that provides an environment for central center workers to operate the equipment through a communication network. In addition, the remote sub-device receives a command from the feeder for remote operation of the on-site power equipment to enable the on-site power equipment.

Through these SCADA, unmanned operation of various industrial facilities at a long distance is possible, and the application fields are electric power facilities, electric railway facilities, subways, gas network facilities, airport and port facilities, and intelligent building facilities.

In particular, Skada applied to electric power facilities is unattended state information of substation which plays a role of power supply transportation. Analog measurement information (power, voltage, current, frequency related to on / off of switch and power supply transportation) Etc.) and send / receive operation commands (On / Off) for the operation of the on-site power facility.

As such, SCADA is composed of feeder (master, FEP, HMI) and remote sub-devices to monitor, measure and control field equipment to enable automatic unmanned operation environment even at a long distance. Although accuracy of control and smooth execution of the control are being made, the SCADA is composed of electromechanical equipment, and data transmission is performed as follows in the transmission, monitoring, measurement, and control of DNP data of field power facilities. For the change of operation status and control status of the on-site power facility, the remote device collects data and transmits the change status information to the operator working for the unmanned operation by sending it to the power distribution center through the SCADA network. Poetry goes through the opposite process. The protocol used for data processing uses a communication protocol called a DNP protocol. In this way, in the monitoring of the status of on-site equipment changes, measurement information and control commands, the feed distribution center and the remote subsidiary device are in two stages of delivery. In this situation, it is necessary to confirm the health of the data.

In other words, it is not a unified configuration, but a power distribution center and a remote subsidiary configuration, which may cause failure or malfunction of any part of the monitoring and accuracy of measurement data, or may not operate. And in case of a failure, SCADA has its own self-diagnosis function, so when a failure occurs, it provides disability information to employees who operate substation unmanned operation through SCADA. However, the self-diagnosis function is not a self-diagnosis function for the entire operating system, and the fault information transmitted is only a part of the fault information. Through connection with console port provided by remote device, detailed message or event about failure information of Skada facility can be checked.

Skada is a system that enables unmanned operation, and the remote facilities, which are the majority of the facilities that make up Skada, are located remotely. In the event of a remote device failure, it is difficult to operate the unmanned operation for a long time due to the confirmation of the failure information and the recovery of the failure.
