Abstract
A hierarchical power flow control system includes power flow control devices, a communication coordinator and a gateway. The gateway provides diagnostics, prognostics, and health monitoring, and communicates with an external energy management system (EMS). Operation and actions are based on self-health monitoring, self-prognostics, and analysis and prediction processing in the gateway, in communication with the external energy management system.
Claims19
A hierarchical power flow control system for a power grid, comprising:
- a plurality of power flow control devices, each configured to inject reactive power into a power transmission line and including a suite of sensors and actuators controlled by a controller for providing diagnostic log generation and storage, self-prognostics and self-health monitoring;
- a communication coordinator configured to communicate with each of the power flow control devices, and further configured to communicate with a gateway equipped to perform analysis and prediction processing, including diagnostics, prognostics and health monitoring (DPHM);
- wherein user input is directed to the gateway directly, or to an Energy Management System (EMS) residing in an external utility office, wherein the EMS will communicate the user input to the gateway in the form of queries or commands.
A method for diagnostics, prognostics, and health monitoring (DPHM) of a distributed power flow control network, comprising:
- communicating regarding self-health monitoring and self-prognostics from a plurality of power flow control devices to a gateway;
- performing analysis and prediction processing at the gateway, based on the self-health monitoring and self-prognostics from the plurality of power flow control devices;
- communicating from the gateway to an external energy management system regarding the self-health monitoring and self-prognostics, the analysis and the prediction processing;
- and
- operating the plurality of power flow control devices through the distributed power flow control network with diagnostics, prognostics, and health monitoring actions based on the self-health monitoring and self-prognostics of the plurality of power flow control devices, the analysis and prediction processing of the gateway, supported by communications with an external energy management system.
A method for diagnostics, prognostics, and health monitoring (DPHM) of a distributed power flow control network, comprising:
- providing a plurality of power flow control devices connected by a power flow control network in the form of a mesh network;
- providing in each of the plurality of power flow control devices a plurality of sensors, a plurality of actuators, and a controller coupled to the plurality of sensors and to the plurality of actuators;
- and
- operating the distributed power flow control network including continuous and periodic and trigger-based and request-based DPHM actions in the plurality of power flow control devices.
