Patent ID: 8482290

Claim:
A system for detecting a line disturbance in a line power to at least a portion of a building and coordinating a response for energy-consuming loads in the building, the system comprising: a load control device adapted to communicate with one or more energy consuming devices, the load control device having a load control device firmware adapted to receive and process control directives to change the load of at least one energy consuming device; and a central control point associated with the building and connected to the line power, the central control point including: one or more electrical circuits including a central point firmware, the central control point firmware adapted to detect the line disturbance, the central control point firmware being in communication with the load control device firmware and adapted to transmit the control directives to the load control device firmware, and at least one circuit adapted to monitor the line power that includes: a signal splitter adapted to derive a first waveform and a second waveform from the line power; a power supply adapted to derive a DC power from the first waveform and adapted to deliver the DC power to the one or more electrical circuits; and a filter and waveform conditioner adapted to derive a low-noise waveform from the second waveform and to transmit the low-noise waveform to a microprocessor for use by a digital signal processor adapted to detect the line frequency and voltage anomalies.
