Problems solved by technology

However, with this method, the control center in the power network directly performs state estimation on the measurement data collected by each PMU, and it is necessary to uniformly perform state estimation on the measurement data collected by each PMU, and uniformly search for PMUs that have been invaded by false data and the The node where the PMU is located. In t

Abstract

The invention discloses a false data intrusion detection method in a power network. Each node in the power network is provided with a PMU and a monitor connected to the PMU, the voltage stability index value of each node is calculated by the monitor installed at each node by employing the measurement data collected by the corresponding PMUs, equivalently, the calculation amount of the control center is distributed to each node for calculation to reduce the calculation amount of the control center so as to correspondingly improve the efficiency of searching the node where the PMU with false data intrusion is located, achieve the purpose of timely searching the PMU with false data intrusion and avoid the problem that the whole power network is paralyzed in system caused by the false data intrusion of the PMU. Besides, the present invention further discloses a false data intrusion detection apparatus and device in a power network having the effects mentioned above.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a false data intrusion detection method, device and equipment in a power network. Background technique [0002] The smart grid realizes the safe and reliable operation of the power network by integrating physical power transmission, communication and network computing, but its dependence on data communication makes it vulnerable to cyber-physical attacks. The complexity of the smart grid requires the power network control center to control and process more equipment and real-time monitoring information. Among them, the Wide Area Measurement System (Wide Area Measurement System) based on the Phasor Measurement Unit (PMU) WAMS) can realize the synchronous real-time monitoring of the power network on the time scale of milliseconds, and its distributed structure can reduce the computing burden of the control center. However, there are corresponding potential threats, such as net...
