M‑5625 Digital Synchronizing System

Digital Synchronizing SystemWhen the M-3410A relay is connected with Line-Line voltage input, the following functions are available (refer to Figure 7 for wiring connections).

• Sync-check with Phase Angle, ∆V and ∆F with dead line/dead bus options (25)

• Reconnect enable (79) for intertie application

• Phase undervoltage (27) detection

• Dual-setpoint, single or three phase, directional power monitoring that can be selected as over power or under power (32) detection (requires current transformer input)

• Negative sequence overvoltage (47) detection

• Phase overcurrent (51) detection (requires current transformer input)

• Phase overvoltage (59) detection

• VT fuse-loss detection and blocking (60FL)

• Four-step over/under frequency (81) detection

If a line-neutral is applied to the single VT input of the M-3410A only the Synch-Check (25) Function is viable. The (51) Function may also be active for this voltage configuration if current input is connected as well (refer to Figures 5 and 6).

Standard Features • Selectable Anti-Motoring and Anti-Pump

• Adjustable Jog Durations, proportional to error, for Voltage and Speed Controls

• Time Between Jogs adjustments bring the generator to a matched condition in minimum time and eliminate overshoot and hunting by accounting for inertial and control lags

• Kicker Pulse brings phase angle around through zero if speed is matched but synchronism has not yet occurred. Adjustable pulse duration compensates for the sensitivity of the governor.

• One Auto-sync output, two Sync-check outputs, one self-test output, two enable inputs, and two control/status inputs

• Oscillographic recording (COMTRADE file format)

• Time-stamped sequence of events recording for 32 events

• Metering of Voltage, Delta Voltage, Frequency, Delta Frequency, Phase Angle, Current and Sync Scope indication

• One RS-232 port (COM1) on front and one RS-232 or 485 port (COM2) on rear

• M-3810A IPScom® For WindowsTM Communications Software

• MODBUS protocol

• Supports both 50 and 60 Hz applications

• Accepts 1A or 5 A rated CT inputs

DescriptionThe M-5625 Syncrocloser Digital Synchronizing System is suitable for the automatic synchronizing of a generator to the electric power network. The system provides speed and voltage “jogs” to bring a generator to proper conditions of matching voltage and frequency, prior to safely and accurately closing a breaker into a bus energized by an electric power network.

The Digital Synchronizing System is intended for three general classes of application:

• Initial connection of a generator to a power network as shown in Figure 1

• Closure of a network breaker where there is a possibility of a split of the system into two isolated networks having different frequencies

• Breaker closure applications with a static phase angle (see Figure 2 Automatic Synchronizing for Synchronous and Asynchronous lines and Bus bars)

The system can also be used for manual synchronizing application. A typical Control Wiring Diagram of Generator Synchronizing System is illustrated in Figure 3.

Minimum Frequency DifferenceThe guaranteed minimum frequency difference for Auto-Sync operation is 0.0005 Hz. However, typical units consistently operate with frequency difference of 0.0001 Hz.

Zero Phase PredictionFigure 4 illustrates the average closing phase error as a function of frequency difference for 80 ms, 100 ms, 200 ms, 400 ms and 800 ms breaker closing times. This data was taken under lab conditions with a constant frequency difference.

Anti‑MotoringThe Anti-Motoring feature prevents closing of the breaker when the generator frequency is slower than the line/system frequency, thus preventing motoring power from flowing into the generator. This function is enabled by an internal toggle switch. The default toggle switch position is "OFF" (disabled).

Anti‑PumpThe breaker close contact of the automatic synchronizer will close for approximately 0.5 second. Power supply to the automatic synchronizer must be removed for approximately 10 seconds before another closure is possible, regardless of the other inputs. A front panel LED (M-0193B READY) indicates that the automatic synchronizer is active and ready to operate, provide input conditions meet their respective limits. The automatic synchronizer can be ordered without the Anti-Pump Option. In this case, the automatic synchronizer will close once on each slip cycle when all input conditions are within their limits and the unit is enabled. The anti-pump option must be specified on order.

Operator Window OptionThe Operator Window Option allows an operator to work in conjunction with the automatic synchronizer. The operator’s contact must be closed within a variable time and phase angle “window”, otherwise the automatic synchronizer will block closing of the breaker. The unit will then automatically reset for the next attempt to close. The operator window option must be specified on order.

MeteringThe Digital Synchronizing System provides metering of voltages, currents, real power, reactive power, power factor, frequency and positive sequence impedance.

Metering Accuracies are:

Voltage: 0.5 V or 0.5%, whichever is greater (Range 0 to 600 V)

Current: 5 A rating, 0.1 A or 3%, whichever is greater (Range 0 to 14 A) 1 A rating, 0.02 A or 3%, whichever is greater (Range 0 to 2.8 A)

Power: 0.02 PU or 2%, whichever is greater

Frequency: 0.03 Hz (from 57 to 63 Hz for 60 Hz models; from 47 to 53 Hz for 50 Hz models)

Sync Scope: The Sync Scope screen displays a phasor representation, the phase angle, delta voltage and delta frequency of generator and incoming voltages. The display should not be used to determine in phase conditions for manual synchronizing because of communications time delay.

Oscillographic RecorderThe oscillographic recorder provides comprehensive data recording of all monitored waveforms, input contacts and output contacts, storing up to 120 cycles of data. The total record length is configured for one or two partitions. A programmable post trigger delay (5 to 95%) is incorporated to capture breaker operation. The oscillograph is triggered either remotely using the serial interface, or designated status input signals or M-5625 programmable output operations. Storage of oscillographic records is nonvolatile, and will be retained even without power, as long as the on-board battery is healthy.

Oscillographic data can be downloaded using serial communication in Common Format For Transient Data Exchange (COMTRADE) format as specified by IEEE Standard C37.111-1999.

Sequence of EventsA total of 32 nonvolatile events can be stored. The recorded information includes the function(s) operated, the function(s) picked up, input/output contact status and time stamp. The events can be retrieved through the communications port. After the 32nd event is stored, additional events result in the oldest event being dropped (FIFO). The information is time-stamped to 1 ms resolution.

CalculationsCurrent and Voltage Values: Uses discrete Fourier transform (DFT) algorithm on sampled (32 times per cycle) voltage and current signals to extract fundamental frequency phasors for calculations. When set for RMS measurement, uses a time domain algorithm to calculate the voltage magnitude.

Power InputNominal 120 V ac, 50/60 Hz, 100 to a maximum of 140 V ac, 22 VA maximum burden at 120 V ac.

Other power input options are available for M-3410A only:

Nominal Range Burden12/24 V dc 9 to 36 V dc <5 VA

48 V dc 36 to 75 V dc <5 VA120 V ac/125 V dc 85 to 150 V ac/V dc <5 VA

–11–


Sensing Inputs 2 Voltage Inputs: Gen/Line and Bus voltages, nominal 120 V ac, 60 Hz (Optional 50 Hz user configurable). Will withstand 145 V ac maximum continuous voltage, 200 V ac for 1 second. Voltage transformer burden less than 0.5 VA at 120 V ac.

3 Current Inputs: Rated current (IR) of 5.0 A or 1.0 A, 60 Hz (50 Hz user configurable). Will withstand 2 IR continuous current and 30 IR for 2 seconds. Current transformer burden is less than 0.75 VA at 5 A for 5 A inputs, 0.3 A at 1 A for 1 A inputs.

Control/Status Inputs • The status inputs, INPUT1 (breaker status 52) and INPUT2 (Auto-Sync close command), can be

used to trigger the oscillograph recorder. The control status inputs accept only dry contacts and are internally wetted by the relay’s power supply. A minimum current of 1.3 mA is required to avoid spurious triggering of the input.

• Enable Auto-Sync close

• Enable Generator Control Unit for speed and voltage matching

• Breaker closing time: field programmable from 20 to 800 ms

Output ContactsAuto‑Sync Close Output: Output will close for approximately 0.5 second. Normally-open dry output contact rated to make and carry 20 A up to 250 V dc, interrupt 0.9 A, 120 V dc inductive load; 0.4 A, 250 V dc inductive load.

Raise and Lower Voltage Jog Outputs, Raise and Lower Speed Jog Outputs: Normally-open dry output contact rated to make and carry 20 A up to 250 V dc, interrupt 0.9 A, 120 V dc inductive load; 0.4 A, 250 V dc inductive load.

Sync Check Close Outputs: Two programmable output relays, each with a contact are rated as per ANSI/IEEE C37.90-1989 for tripping: make 30 A for 0.2 seconds. Available hardware configurations include two normally open (Option B1), one normally open and one normally closed (Option B2), or two normally closed (Option B3) contacts. The contacts will carry 8 A, break 6 A at 120 V ac, break 0.1 A at 125 V dc, inductive break 0.1 A. Also provided is a self-test alarm output contact (form 'c') with a rating of 8 A at 120 V ac, 5 A at 30 V dc, 125 V dc 0.15 A resistive, 0.1 A inductive.

Any of the M-3410A protective functions can be individually programmed to activate the two programmable outputs. The user can configure the two programmable outputs to either energize or de-energize to issue an output command.

The outputs (excluding the self-test) can have two modes of operation, LATCHING and NORMAL. The LATCHING mode requires an operator intervention to deactivate the outputs after the condition for operation has been removed. In the NORMAL mode, when the condition for tripping has been removed, the output(s) will deactivate automatically after the corresponding seal-in timers have expired.

Status Output ContactsrV Status Output: Closed when rV (delta voltage) is within limits. Normally-open dry output contact rated 0.5 A at 125 V dc resistive, 1 A at 120 V ac or 250 V dc across open contact.

rF Status Output: Closed when rF (delta frequency) is within limits. Normally-open dry output contact rated 0.5 A at 125 V dc resistive, 1 A at 120 V ac or 250 V dc across open contact.

Auto‑Sync Close Status Output: Closed when Auto-Sync closed command is issued. Normally-open dry output contact rated 0.5 A at 125 V dc resistive, 1 A at 120 V ac or 250 V dc across open contact.

Self‑Test Alarm Output: Form ‘c’ dry output contact with rating of 8 A at 120 V ac, 5 A at 30 V dc, 125 V dc 0.15 A resistive, 0.1 A inductive.

The Status Output Contacts are light duty contacts intended primarily for status interrogation by supervisory control. They can be used to illuminate local lamps within the above maximum ratings.
