20080288118 | Network radiality in reconfiguration of a radial power distribution system using a matrix-structured knowledge-based system - The radial distribution system is the most commonly used power distribution system, but lacks reliability because there is only one power source for a group of customers. A knowledge-based system is defined that ensures network radiality during reconfiguration of a power distribution system. Network radiality heuristics identify a pair of switching operations that will preserve radiality. A line section table specifies the line section identifier, start bus, end bus, line section type, and switch existence for each line section in the network. A bus table identifies the line section that supplies the bus and those line sections that are fed by the bus for each bus in the network. A matrix-structured knowledge base with five distinct rule bases is used. Rule base A is used in determining which other rule bases to activate. Rule base B is used in considering whether to open a switch and rule base C is used during a breadth first search in finding a corresponding initially open switch to close to assume the load transfer that would be necessitated by the switch opening. Rule base D is used in considering whether to close a switch and rule base E is used during a breadth first search in finding a corresponding initially closed switch to open because of the load transfer that would be necessitated by the switch closing. The line section and bus tables must be updated after any switching operations are enacted. Extensive simulations of the knowledge-based system revealed that a solution was found in a time-efficient manner. This knowledge-based system enhances network reliability and hence prevents power outages. Also, the knowledge-based system can be used to preserve radiality during optimization of power distribution system operations for different objectives. | 11-20-2008 |
20140032138 | APPARATUS AND METHOD FOR OUT-OF-STEP PROTECTION USING THE ANALYSIS OF TRAJECTORIES OF ELECTRICAL MEASUREMENTS IN STATE PLANE - Various embodiments are described herein for a device and method for predicting an out-of-step or transient instability condition in a power system due to a disturbance, such as a fault, where the power system comprises a power generator. The method comprises determining values for a state plane trajectory for the power generator during the disturbance based on using an internal voltage angle of the power generator or an equivalent power generator and a during fault rotor speed of the power generator or equivalent power generator as state variables, determining time scale values; determining values for a critical state plane trajectory for the power generator after clearing the fault, determining values for a state plane trajectory for the power generator after clearing the fault, determining a critical clearing angle and a critical clearing time, and predicting that the power generator will be stable or unstable by comparing the time to clear the fault with the critical clearing time. | 01-30-2014 |
