MeasurementValueQuality

Measurement quality flags. Bits 0-10 are defined for substation automation in IEC 61850-7-3. Bits 11-15 are reserved for future expansion by that document. Bits 16-31 are reserved for EMS applications.

Inheritance

Attributes

Name URI Cardinality and Range Description Inheritance
MeasurementValue cim:MeasurementValueQuality.MeasurementValue No cardinality available MeasurementValue A MeasurementValue has a MeasurementValueQuality associated with it. direct
badReference cim:Quality61850.badReference No cardinality available boolean Measurement value may be incorrect due to a reference being out of calibration. Quality61850
estimatorReplaced cim:Quality61850.estimatorReplaced No cardinality available boolean Value has been replaced by State Estimator. estimatorReplaced is not an IEC61850 quality bit but has been put in this class for convenience. Quality61850
failure cim:Quality61850.failure No cardinality available boolean This identifier indicates that a supervision function has detected an internal or external failure, e.g. communication failure. Quality61850
oldData cim:Quality61850.oldData No cardinality available boolean Measurement value is old and possibly invalid, as it has not been successfully updated during a specified time interval. Quality61850
operatorBlocked cim:Quality61850.operatorBlocked No cardinality available boolean Measurement value is blocked and hence unavailable for transmission. Quality61850
oscillatory cim:Quality61850.oscillatory No cardinality available boolean To prevent some overload of the communication it is sensible to detect and suppress oscillating (fast changing) binary inputs. If a signal changes in a defined time twice in the same direction (from 0 to 1 or from 1 to 0) then oscillation is detected and the detail quality identifier "oscillatory" is set. If it is detected a configured numbers of transient changes could be passed by. In this time the validity status "questionable" is set. If after this defined numbers of changes the signal is still in the oscillating state the value shall be set either to the opposite state of the previous stable value or to a defined default value. In this case the validity status "questionable" is reset and "invalid" is set as long as the signal is oscillating. If it is configured such that no transient changes should be passed by then the validity status "invalid" is set immediately in addition to the detail quality identifier "oscillatory" (used for status information only). Quality61850
outOfRange cim:Quality61850.outOfRange No cardinality available boolean Measurement value is beyond a predefined range of value. Quality61850
overFlow cim:Quality61850.overFlow No cardinality available boolean Measurement value is beyond the capability of being represented properly. For example, a counter value overflows from maximum count back to a value of zero. Quality61850
source cim:Quality61850.source No cardinality available Source Source gives information related to the origin of a value. The value may be acquired from the process, defaulted or substituted. Quality61850
suspect cim:Quality61850.suspect No cardinality available boolean A correlation function has detected that the value is not consistent with other values. Typically set by a network State Estimator. Quality61850
test cim:Quality61850.test No cardinality available boolean Measurement value is transmitted for test purposes. Quality61850
validity cim:Quality61850.validity No cardinality available Validity Validity of the measurement value. Quality61850
