Abstract

A system for monitoring a power transmission line includes at least one monitoring device located along the power transmission line configured to provide power transmission line data. A wide area situational awareness module is configured to receive the power transmission line data and an adaptation module is configured to receive output from the wide area situational awareness module and further configured to calculate control actions for the power transmission line based on the power transmission line data.

Claims

1. ) A system for monitoring a power transmission line, said system comprising:

at least one monitoring device located along said power transmission line configured to provide power transmission line data;

a wide area situational awareness module configured to receive said power transmission line data; and

an adaptation module configured to receive output from said wide area situational awareness module and further configured to calculate control actions for said power transmission line based on said power transmission line data.

2. ) The system as claimed in claim 1, further comprising a plurality of monitoring devices, each located along said power transmission line and each configured to provide power transmission line data.

3. ) The system as claimed in claim 2, wherein said plurality of monitoring devices includes dynamic line rating devices and phasor measurement units.

4. ) The system as claimed in claim 3, wherein said wide area situational awareness module is configured to receive said power transmission line data from said dynamic line rating devices and said phasor measurement units and to combine a current transmission line state determined from said power transmission line data with static and dynamic power transmission line equipment limits.

5. ) The system as claimed in claim 4, wherein said output from said wide area situational awareness received by said adaptation module is said transmission line state and said static and dynamic power transmission line equipment limits,

wherein said adaptation module is configured to calculate control actions for said power transmission line based on such transmission line state and said static and dynamic power transmission line equipment limits.

6. ) The system as claimed in claim 5, wherein transmission line state, determined by wide area situational awareness module and received by said adaptation module includes at least a plurality of optimizable criteria, including at least criteria related to transmission line system reliability, transmission line operation cost, and transmission line efficiency.

7. ) The system as claimed in claim 6, wherein said adaptation module is configured to select at least one optimizable criterion from the available optimizable criteria to optimize using said calculated control actions.

8. ) The system as claimed in claim 7, wherein said calculated control actions are provided to a system operator as advisory actions.

9. ) The system as claimed claim 7, wherein said calculated control actions are provided directly to controllable transmission line operation equipment.

10. ) The system as claimed in claim 7, wherein said calculated control actions for said power transmission line generated by said adaptation module are arranged to optimize and/or supplant off-line worst case scenario (N-1) standards with on-line real time control actions based on real-time power transmission line capacity and environmental factors.

11. ) The system as claimed claim 7, wherein said calculated control actions for said power transmission line generated by said adaptation module are arranged to optimize and/or supplant off-line worst case scenario (N-1-1) standards relating to first and second contingencies, with on-line real time control actions based on real-time power transmission line capacity and environmental factors, such that after a first contingency, a transmission line system operator can adjust transmission line equipment bring said transmission line back to a less vulnerable state using a in smaller reserve requirement than if settings of said transmission line equipment were only adjusted off-line based on said worst case scenario standard.
