Section 3 1MRK 502 048-UUS A Analog inputs Section 3 Analog inputs Introduction Analog input channels in the IED must be set properly in order to get correct measurement results and correct protection operations. For power measuring and all directional and differential functions the directions of the input currents must be defined in order to reflect the way the current transformers are installed/connected in the field ( primary and secondary connections ).

Section 7 1MRK 502 048-UUS A Impedance protection 7.4.7 Operation principle General Under balanced and stable conditions, a generator operates with a constant rotor angle (power angle), delivering active electrical power to the power system, which is approximately equal to the input mechanical power on the generator axis, minus the small losses in the generator.

If the generator is not immediately disconnected, it then continues pole-slipping — see Figure 76, where two pole-slips (two pole-slip cycles) are shown. Under out-of-step conditions, the centre of oscillation is where the locus of the complex impedance Z(R, X) crosses the (impedance) line connecting the points SE (Sending End), and RE (Receiving End).

(To require that the impedance Z(R, X) travels through each of the two halves of the lens, for example, in 25 milliseconds, results in a tendency to miss the 1st pole-slip, that one immediately after the fault has been cleared.)

Page 380 Section 12 1MRK 502 048-UUS A Control In the supervision phase, the switch controller function evaluates the "cause" values from the switch modules Circuit breaker (SXCBR)/ Circuit switch (SXSWI). At error the "cause" value with highest priority is shown. Blocking principles The blocking signals are normally coming from the bay control function (QCBAY) and via the IEC 61850 communication from the operator place.

Section 12 1MRK 502 048-UUS A Control Error handling Depending on the error that occurs during the command sequence, the error signal will be set with a value. Table describes vendor specific cause values in addition to these specified in IEC 61850-8-1 standard. The list of values of the “cause” are in order of priority.
Page 384 Section 12 1MRK 502 048-UUS A Control for the local/remote switch is not valid the PSTO output will always be set to faulty state (3), which means no possibility to operate. To adapt the signals from the local HMI or from an external local/remote switch, the function blocks LOCREM and LOCREMCTRL are needed and connected to QCBAY.

Section 12 1MRK 502 048-UUS A Control The switching of the Local/Remote switch requires at least system operator level. The password will be requested at an attempt to operate if authority levels have been defined in the IED. Otherwise the default authority level, SuperUser, can handle the control without LogOn.

Section 12 1MRK 502 048-UUS A Control 12.3 Interlocking 12.3.1 Functionality The interlocking functionality blocks the possibility to operate high-voltage switching devices, for instance when a disconnector is under load, in order to prevent material damage and/or accidental human injury. Each control IED has interlocking functions for different switchyard arrangements, each handling the interlocking of one bay.

Section 12 1MRK 502 048-UUS A Control 12.3.2.4 Logic diagram The function contains logic to enable the open and close commands respectively if the interlocking conditions are fulfilled. That means also, if the switch being controlled has its position defined as open (via POSOPEN) for example, then the appropriate enable signal output (in this case EN_OPEN) is false.

Section 14 1MRK 502 048-UUS A Monitoring The IED flash disk should NOT be used to store any user files. This might cause disturbance recordings to be deleted due to lack of disk space. 14.4.6.1 Disturbance information Date and time of the disturbance, the indications, events, fault location and the trip values are available on the local HMI.

Section 14 1MRK 502 048-UUS A Monitoring 14.4.6.9 Analog signals Up to 40 analog signals can be selected for recording by the Disturbance recorder and triggering of the Disturbance report function. Out of these 40, 30 are reserved for external analog signals from analog input modules via preprocessing function blocks (SMAI) and summation block (3PHSUM).

Connect the signals to the AxRADR accordingly.
Page 580: Post Retrigger
Section 14 1MRK 502 048-UUS A Monitoring A trigger can be of type: • Manual trigger • Binary-signal trigger • Analog-signal trigger (over/under function) Manual trigger A disturbance report can be manually triggered from the local HMI, PCM600 or via station bus (IEC 61850).
Page 581: Technical Data
Section 14 1MRK 502 048-UUS A Monitoring In order to capture the new disturbance it is possible to allow retriggering (PostRetrig = Enabled) during the post-fault time. In this case a new, complete recording will start and, during a period, run in parallel with the initial recording. When the retrig parameter is disabled (PostRetrig = Disabled), a new recording will not start until the post-fault (PostFaultrecT or TimeLimit) period is terminated.

Section 14 1MRK 502 048-UUS A Monitoring 14.5 Indications 14.5.1 Functionality To get fast, condensed and reliable information about disturbances in the primary and/or in the secondary system it is important to know, for example binary signals that have changed status during a disturbance. This information is used in the short perspective to get information via the local HMI in a straightforward way.

Section 14 1MRK 502 048-UUS A Monitoring 14.9 Disturbance recorder 14.9.1 Functionality The Disturbance recorder function supplies fast, complete and reliable information about disturbances in the power system. It facilitates understanding system behavior and related primary and secondary equipment during and after a disturbance. Recorded information is used for different purposes in the short perspective (for example corrective actions) and long perspective (for example functional analysis).
Page 589: Memory And Storage
Section 14 1MRK 502 048-UUS A Monitoring Disturbance recorder collects analog values and binary signals continuously, in a cyclic buffer. The pre-fault buffer operates according to the FIFO principle; old data will continuously be overwritten as new data arrives when the buffer is full. The size of this buffer is determined by the set pre-fault recording time.
Page 590 Section 14 1MRK 502 048-UUS A Monitoring The header file (optional in the standard) contains basic information about the disturbance, that is, information from the Disturbance report sub-functions.
