The analog generation of the busbar differential IEDs ( KA2, 87B, RADHA, RADSS, REB 103) generally solves all these problems caused by the CT non-linear characteristics by using the galvanic connection between the secondary circuits of all CTs connected to the protected zone.

K Section 20 Basic IED functions 20.11.2 Frequency values GUID-B494B93C-B5AA-4FD6-8080-8611C34C2AD8 v5 The SMAI function includes a functionality based on the level of positive sequence voltage, MinValFreqMeas, to validate if the frequency measurement is valid or not. If the positive sequence voltage is lower than MinValFreqMeas, the function freezes the frequency output value for 500 ms and after that the frequency output is set to the nominal value.
Page 476 Section 20 1MRK 505 370-UUS Rev. K Basic IED functions However, this configuration, combined with unbalanced three-phase input, results in incorrect calculated phase-earth values. This in turn may result in maloperation of functions connected to SMAIs configured in this way, if the function uses phase-earth based values.
Page 477 1MRK 505 370-UUS Rev. K Section 20 Basic IED functions Even if the user sets the AnalogInputType of a SMAI block to “Current”, the MinValFreqMeas is still visible. However, using the current channel values as base for frequency measurement is not recommendable for a number of reasons, not last among them being the low level of currents that one can have in normal operating conditions.

In practice each instance can be adapted to the needs of the actual application. The adaptive frequency tracking is needed in IEDs that belong to the protection system of synchronous machines and that are active during run-up and shout-down of the machine.

Page 485 1MRK 505 370-UUS Rev. K Section 20 Basic IED functions IEEE 1588 (PTP) PTP according to IEEE 1588-2008 and specifically its profile IEC/IEEE 61850-9-3 for power utility automation is a synchronization method that can be used to maintain a common time within a station. This time can be synchronized to the global time using, for instance, a GPS receiver.
Page 486 Section 20 1MRK 505 370-UUS Rev. K Basic IED functions The function input to be used for minute-pulse synchronization is called BININPUT. For a description of the BININPUT settings, see the Technical Manual. The system time can be set manually, either via the local HMI or via any of the communication ports. The time synchronization fine tunes the clock (seconds and milliseconds).

Page 488 Section 20 1MRK 505 370-UUS Rev. K Basic IED functions If PTP is not used, use the same synchronization method for the HwSyncSrc as the merging unit provides. For instance, if the merging unit provides PPS as synchronization, use PPS as HwSyncSrc. If either PMU or LDCM in GPS-mode is used, that is, the hardware and software clocks are connected to each other, HwSyncSrc is not used and other means to synchronize the merging unit to the IED is required.

K Section 21 Requirements Section 21 Requirements 21.1 Current transformer requirements IP15171-1 v2 M11609-3 v2 The performance of a protection function will depend on the quality of the measured current signal. Saturation of the current transformers (CTs) will cause distortion of the current signals and can result in a failure to operate or cause unwanted operations of some functions.
