Abstract
System and methods for coordinating the control system of a switched power capacitor with an integrated resonance protection function. The coordination system coordinates the function of a switched power capacitor's primary control system and resonance protection system to avoid duplication of tasks and on/off operation deadlock. The coordination system adjusting calculations made by the primary control system in response to a determination of a harmonic resonance condition by the resonance protection system.
Claims20
A method for coordinated control of a switched power capacitor with an integrated resonance protection function, comprising the steps of:
- A. receiving control parameters and an indication of whether a harmonic resonance condition is present;
- B. if a harmonic resonance condition is present, then adjusting said control parameters;
- and
- C. performing capacitor switching operations based on said control parameters and returning to step A.
A system for coordinated control of a switched power capacitor with an integrated resonance protection function, comprising a control processor programmed to perform the following process:
- A. receive control parameters and an indication of whether a harmonic resonance condition is present;
- B. if a harmonic resonance condition is present, then adjust said control parameters;
- and
- C. perform capacitor switching operations based on said control parameters and return to step A.
