Cyber-Physical System Model for Monitoring and Control

National Energy Technology Laboratory

Contact NETL About This Technology

Technology Marketing Summary

Research is active on the design of a cyber-physical system to monitor and exert control over multistage networked plants and processes such as multistage chemical processing plants and power generation facilities. This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.

Description

This invention is the use of a cyber physical model (CPM) to monitor information from power plant operations, interpret discrepancies in real time, and asses the process state for potential process instabilities. CPM consists of both hardware components and virtual models that operate in real-time alongside the operating plant to emulate the processes taking place in the process unit while also assessing data for integrity and for any indication that processes have been compromised or are becoming unstable.

This invention addresses vulnerabilities to multistage and networked processes, including the risks associated with cyber-attacks, fault detection, and sabotage. CPM combines and couples hardware to emulate the critical dynamic components and unpredictable fluid dynamics components in a multistage or networked system with software to evaluate the fluid dynamic similarities, emulate the predictable components, identify the differences from the plant’s operating map, and to exert supervisory control over when necessary.

Benefits

Emulates critical dynamic components

Addresses system vulnerabilities

Potentially simplifies and speeds up the detectability and increase the accuracy of numerical approaches

CYBER-PHYSICAL SYSTEM MODEL FOR MONITORING AND CONTROL
Materials, methods to prepare, and methods for evaluating and controlling a multistage/networked system. The system includes a power component; a controller coupled to the power component enabled for remote access through the internet; and sensor(s) coupled to one of the power component and the controller. The system further includes a cyber physical module (CPM) including hardware modules and virtual model coupled to one of the power components, controller and the sensor(s). The method includes receiving reading(s) from the power component and the sensor(s) using the controller; receiving reading(s) from the power component and the sensor(s) in real-time using the CPM; emulating dynamic components and unpredictable fluid dynamic components in the system using the CPM; evaluating fluid dynamic similarities to identify differences from a system map using the CPM; determining any deviations from the system map using the CPM; and breaking a connection to the remote access and asserting supervisory control over the system using the CPM.
