GE Multilin F60 Feeder Protection System 5-1155 SETTINGS 5.4 SYSTEM SETUP5Depending on the applied filter, the Synchrophasors that are produced by PMUs are classified as either P (protection) or M(Measurement) class Synchrophasors. Synchrophasors available within the UR that have no filtering applied are classifiedas NONE which within the standard is classified as PRES OR UNKNOWN under the Calculation Method - ClcMth. EachLogical Device PMU supports one MxxMMXU, MxxMSQI, PxxxMMXU , PxxxMSQI, NxxMMXU, and one NxxMSQI logicalnode.Figure 5–43: LOGICAL NODES SUPPORTED IN EACH LOGICAL DEVICEThe following is a summary of LNs that are in each Logical Device (LD2 through LD5):- PxxxMMXU1 ClcMth = P-Class (Note Vaux is mapped to Vneut of MMXU)- PxxxMSQI1 ClcMth = P-CLASS- MxxMMXU1 ClcMth = M-Class (Note Vaux is mapped to Vneut of MMXU)- MxxMSQI1 ClcMth = M-CLASS- NxxMMXU1 ClcMth = M-Class (Note Vaux is mapped to Vneut of MMXU)- NxxMSQI1 ClcMth = M-CLASS- GGIO1 which contains 16 digital status indication points and 16 analog points. The Analog GGIO values are selectablefrom any FlexAnalog value in the UR.The Synchro Logical Nodes in an LD report at the same rate as set in the PMUn Basic Configuration setting. This isreflected in the instantiation of the Data Object – SmpRate in the msvcb## of LLN0 in the LD1. SmpRate is a ReadOnly Integer Status (INS).When the first PMU from any LD is mapped into an aggregator, the aggregator inherits the Sample Rate (SmpRate) andIEEC C37.118 Class (P or M) of that PMU. The value of the SmpRate DO in the Report Control Block is set based on thevalue of the Sample Rate in the PMU. The Class of the Dataset are mapped into the MSVID of the Dataset (see text belowfor the overall name of the MSVID). If other PMUs are mapped into the same aggregator with different Sample Rates orfrom different classes, then a Self-Test error (DatSetErr) is set and dataset transmission is blocked.A setting value – MSVID – is created with a maximum input range of 56 characters (=64 less 6 for the IDCode less 2 for theClass).The value of MSVID in the dataset is a concatenation of the aggregator IDCode and the MSVID setting value in the format:MSVID-AggregatorIDCode-CLASS where CLASS is P, M, or N (for None) – depending on the Class of the first PMUincluded in the Aggregator.Synchrophasor Rectangular Format and Integer data types are NOT supported in IEC 61850-90-5 (only supportedwith IEEE C37.118) and not to set — GGIO1 which contains 16 digital status indication points — aggregated as a16 bit bitstring and 16 analog points. The Analog GGIO values are selectable from any FlexAnalog value in the UR.For version 7.0 and later the description fields for the phasors, analog and digital channels are populated with the16 character name field provided within the Basic Configuration menu. Additionally, the names of the 16 binarypoints are implemented as numbered descriptions — d1, d2, d3, and so on. The number of descriptions are equalto the number of bits configured in the 16 bit digital status word.NOTENOTE
