A wind turbine generator control system is provided for controlling output of a plurality of tightly-coupled windfarms connected at a point of common coupling with a power system grid. A master reactive control device employs algorithms whose technical effect is to coordinate the real power, reactive power and voltage output of the multiple windfarms. The controller incorporates a reactive power regulator that can be used to regulate reactive power, power factor or voltage at the point of common coupling and an active power regulator that can be used to regulate real power at the point of common coupling; such that each windfarm is not asked to contribute or violate its own operating capability.

Arena locations are selected by chances sold to customers for recording and distributing video images of the location. A vend terminal/processor system is used to sell these chances and load them to a chance table. The chance table is accessed by a camera control processor and a response control processor to cause a video camera to record and transmit images of selected arena locations selectively to a TV live or delayed broadcast, a view screen at the arena, or to a remote customer for viewing at a display.

The invention relates to a resource allocation method. A base station utilizes a control channel unit of a physical downlink control channel to transmit control signaling related to the downstream data to a mobile terminal; after the mobile terminal receives the control signaling, the mobile terminal obtains virtual resource block index mapped by the corresponding physical uplink response control channel, and physical uplink reply control channel index which is determined by mapped circulating motion amount index and time domain orthogonal code index in the virtual resource block according to the index of the control channel unit, and the set mapping method; the mobile terminal returns positive/negative acknowledgement control signaling on the physical uplink response control channel to the base station; when the set mapping method ensures the physical uplink response control channel corresponding to adjacent control channel unit indexes to be mapped to an identical virtual resource block, the mapped time domain orthogonal code indexes are different or identical, but the circulating motion amount indexes are not adjacent, therefore the interference between the physical uplink response control channels corresponding to the adjacent control channel units is minimized.

A power plant controller (36) is described. The power plant controller (36) controls a power generation system (10) having one or more power generators (12) and an energy storage system (22), and provides a utility grid or transmission system operator with the capability to select the droop response provided by the power generation system.

The proposed Amlev Self-Regulating System of High Speed Ground Transportation Based on Permanent Magnets and Steel Cores is designated for magnetic levitation, stabilization, and propulsion of vehicles moving without friction. The proposed system comprises subsystems: a Magneto-Dynamic Levitation and Stabilizing Self-Regulating System (MDLSS), and a Permanent Magnet Linear Synchronous Motor (PMLSM). Both systems comprise permanent magnets and steel cores. MDLSS provides levitation and stabilization of vehicle while PMLSM produces propulsion force providing the assigned alternative velocity of the vehicle along the stator winding powered by the current of constant frequency 50 Hz. Each of the subsystems comprises two main parts: a fixed part—guideway/stator including extended steel cores for MDLSS and windings for PMLSM, and moving part—permanent magnets of the levitator for MDLSS and the rotor for PMLSM—both affixed to the moving vehicle. Each of the subsystems is self-regulating and operates without fast response control system. A new model is proposed for measuring destabilizing forces impacting a flying vehicle at its shifts from an assigned trajectory that allows to eliminate the stage of full-scale modeling when designing Amlev system.

A voltage control apparatus for an electric generator includes a load response controller and a voltage response controller. The electric generator includes a field winding and is driven by an engine of a motor vehicle. When the output voltage of the generator decreases below a threshold voltage upon the application of an electrical load, the rotational speed of the engine fluctuates to repeatedly increase and decrease until it is stabilized. During the time periods in which the rotational speed of the engine decreases, field current supplied to the field winding of the generator is gradually increased under a load response control performed by the load response controller. During the time periods in which the rotational speed of the engine increases, the field current is gradually increased under a voltage response control by the voltage response controller.

Disclosed is an automatic gain controller capable of reducing signal saturation or signal distortion caused by out-of-band signals of a filter extracting an object signal or delay of a control signal and capable of precisely measuring a signal level in a filter band. An AGC response control section compares a level of control voltage (“V2_I terminal” signal) outputted from a first AGC control section and inputted into a “V2_I terminal” with a level of control voltage (“V3_I terminal” signal) outputted from a second AGC control section and inputted into a “V3_I terminal”.
