Abstract
A control system includes a data monitoring module configured to: obtain one or more status indicators of a voltage regulation system, each status indicator corresponding to an operating parameter of the voltage regulation system; determine a state value of each status indicator at a second time; compare the state value of each status indicator to a state value for that status indicator at a first time, the first time occurring before the second time; determine whether any operating parameter of the voltage regulation system changed state based on the comparison; and if any operating parameter of the voltage regulation system changed state, store a record in a dataset, the record including the state value of all of the status indicators and a time stamp that includes the second time.
Claims17
A control system comprising:
- a data monitoring module configured to:
- obtain one or more status indicators of a voltage regulation system, each status indicator corresponding to an operating parameter of the voltage regulation system;
- determine a state value of each status indicator at a second time;
- compare the state value of each status indicator to a state value for that status indicator at a first time, the first time occurring before the second time;
- determine whether any operating parameter of the voltage regulation system changed state based on the comparison;
- and
- if any operating parameter of the voltage regulation system changed state, store a record in a dataset, the record comprising the state value of all of the status indicators and a time stamp that comprises the second time.
A method comprising:
- monitoring the state of one or more operating parameters of an electrical system during an observation period to detect changes in the state of the one or more operating parameters;
- and
- in response to detecting a change in the state of any of the operating parameters at a time in the observation period:
- generating a record that comprises one or more values and a time stamp, the one or more values each representing the state of one operating parameter at the time in the observation period and the time stamp comprising the time in the observation period;
- and
- adding the generated record to a dataset such that the dataset includes records of state changes.
A system comprising:
- a data management module configured to:
- obtain a dataset comprising records, each record representing a state change of at least one operating parameter of an electrical system, wherein each record comprises state values of the operating parameters and a time stamp, each time stamp being a time when a state change for at least one operating parameter was detected;
- and
- prepare oscillography data from the dataset by generating at least one filler record and adding the least one filler record between a first record in the dataset and a second record in the dataset, the first record having an earlier time stamp than the second record, and the filler record comprising the same state values as the first record and a time stamp between the time stamp of the first record and the time stamp of the second record;
- and
- a visualization module configured to present a graph comprising the values in the oscillography data plotted as a function of time for the observation period.
