Properties

	Name	Description
	Algorithm	Gets or sets the PhaseEstimationAlgorithm used to derive synchrophasor, frequency and ROCOF components from SEL CWS point-on-wave data.
	CalculatePhaseEstimates	Gets or sets flag that determines if current and voltage phase estimates, frequency and dF/dt should be calculated for PoW data.
	CalculationFrameRate	Gets or sets the configured frame rate for phase estimate calculations.
	EnableIntervalAveraging	Gets or sets a flag that determines if interval averaging (boxcar averaging) is enabled across each publish interval when down-sampling.
	EnablePublishEMA	Gets or sets a flag that determines if an additional exponential moving average (EMA) is applied to the published stream (after interval averaging).
	FilterClass	Gets or sets the IEEE C37.118 filter class: P (Protection, fast response) or M (Measurement, better out-of-band rejection).
	MaxGapFillSamples	Gets or sets the maximum gap (in input samples) filled by phase-continued synthesis before resynchronizing.
	NominalFrequency	Gets or sets the nominal LineFrequency of this SEL CWS device.
	PublishAnglesTauSeconds	Gets or sets the EMA time constant τ (seconds) for published phase angles.
	PublishFrequencyTauSeconds	Gets or sets the EMA time constant τ (seconds) for published frequency.
	PublishMagnitudesTauSeconds	Gets or sets the EMA time constant τ (seconds) for published RMS magnitudes.
	PublishRocofTauSeconds	Gets or sets the EMA time constant τ (seconds) for published ROCOF (dF/dt).
	RecalculationCycles	Gets or sets the number of nominal cycles between full DFT recalculations for numerical stability.
	ReferenceChannel	Gets or sets the reference channel for frequency tracking.
	RepeatLastCalculatedValueWhenDownSampling	Gets or sets flag that determines if last value should be repeated when down-sampling, i.e., when CalculationFrameRate is less than SEL CWS frame rate (commonly 3000Hz); otherwise NaN will be used.
	SampleFrequencyTauSeconds	Gets or sets the EMA time constant τ (seconds) for the internal per-sample frequency smoothing that occurs inside the estimator before any down-sampling/publish filtering.
	SampleRocofTauSeconds	Gets or sets the EMA time constant τ (seconds) for the internal per-sample ROCOF smoothing (computed from the internally smoothed frequency).
	TargetCycles	Gets or sets the number of nominal cycles contained in the sliding DFT analysis window.
	ValuesAreValid	Determines if custom connection parameters are valid. (Inherited from ConnectionParametersBase)

Methods

	Name	Description
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetObjectData	Populates a SerializationInfo with the data needed to serialize the target object. (Overrides ConnectionParametersBaseGetObjectData(SerializationInfo, StreamingContext))
	GetType	Gets the Type of the current instance. (Inherited from Object)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	ToString	Returns a string that represents the current object. (Inherited from Object)

Extension Methods

	Name	Description
	GetEnumValueOrDefault	Gets the enumeration constant for value, if defined in the enumeration, or a default value. (Defined by EnumExtensions)
	GetEnumValueOrDefaultT	Gets the enumeration constant for this value, if defined in the enumeration, or a default value. (Defined by EnumExtensions)

Remarks

This class is designed to be exposed by a "PropertyGrid" so a UI can request protocol specific connection parameters. As a result the CategoryAttribute and DescriptionAttribute elements should be defined for each of the exposed properties.
