摘要: A two-level hierarchical control structure for augmenting bulk system transient stabilitiy is described. This involves localized subsystem controllers communicating value demands to an area coordinator. The local controllers, making computations in parallel, use locally available measurements determine the present state a. modified Zaborszky-Subramanian equilibrium frame. Barnard optimal aim strategy then used map this point into a desired value. from each controller communicated coordinator which allocates physical means under its jurisdiction optimally implement these demands. paper deals primarily with design of controllers. The. functional requirements are also Experimental results, using presented concepts obtained on New England 10-machine test system, included These results indicate that substantial augmentation stability margins can be achieved.
