95 results about "Event generator" patented technology

Event generators are software libraries that generate simulated high-energy particle physics events. They randomly generate events as those produced in particle accelerators, collider experiments or the early universe. Events come in different types called processes as discussed in the Automatic calculation of particle interaction or decay article.

Electrical anomaly detection method and system

There are provided a method and a system for real time monitoring of a powered on electrical network in a facility in order to detect an electrical anomaly while the electrical network is in use. The system comprises a sensor data receiver for receiving real time sensor data including at least one measured value measured in real time by at least one sensor installed on a conductor of the electrical network in the facility while the electrical network is in use; an anomaly detector for retrieving an anomaly detection rule from an anomaly detection rule database, the rule having an identification of a required input, a formula, and a threshold reference value, for a detection of an anomaly; receiving the real time sensor data from the sensor data receiver and extracting at least one relevant measured value from the at least one measured value using the identification of the required input; comparing the at least one relevant measured value to the threshold reference value according to the formula to determine one of a presence and an absence of the anomaly in the real time sensor data; an event generator controlled by the processor for retrieving and providing anomaly monitoring data if the anomaly is determined to be present by the processor, the anomaly monitoring data including an indication of a monitoring course of action to be carried out to address the anomaly determined to be present.

Power system control method based on event-triggered dynamic triggering mechanism

The invention discloses a power system control method based on the event-triggered dynamic triggering mechanism. a PMU is connected to a generator for dynamic and real-time monitoring; an output y(t)of the PMU is transmitted to a sensor, wherein the sensor is used for receiving and storing signals; an event generator is introduced after the sensor and a control process is operated by the event generator; a retainer is connected after the event generator and is used for keeping an output y(tk) of the event generator constant in [tk,tk+1] during the process of event triggering sampling; if a dynamic triggering strategy is satisfied, then triggering, i.e., non-uniform sampling, is carried out by the event generator; an output y(tk) is obtained by updating data; then an input u(t) of a controller is updated; finally, the updated input u(t) is transmitted to an executor and returned to the generator to continue updating the output y(t); the above steps are cycled. Compared with the prior art, the invention has the following advantages: the dynamic triggering mechanism relates not only to the current output and error, but also to the previous one; adding internal dynamic variables makesit easier to control and adjust the system's event triggering strategy.
