    Chapter Installation Mounting Requirements This equipment is intended for use in a Pollution Degree 2 Industrial Environment, in overvoltage Category II applications (as defined by IEC publication 60664-1). Because the units contain a heat sink, they must be mounted vertically. Any other mounting angle reduces the heat dissipation capabilities of the units, which can lead to premature failure of critical components.

  • Page 51 CGCM-DLR Unit Operation Chapter 3 Power Factor Regulation Mode (PF) In PF mode, the CGCM-DLR unit controls field excitation current output to maintain the commanded power factor setpoint.

  • Page 53 CGCM-DLR Unit Operation Chapter 3 Internal Tracking The CGCM-DLR unit provides a tracking function between the non-active modes of operation and the active mode of operation. This function minimizes the potential for instability that can occur when switching from one mode to another.

  • Page 54: Limiting Functions

    Chapter 3 CGCM-DLR Unit Operation Limiting Functions This section discusses the different types of limiting functions the CGCM-DLR unit provides. • Volts/Hertz Limit • Over-excitation Limit • Under-excitation Limit Generator Capability Curve The generator capability curve graphically depicts the combinations of real and reactive power a generator is able to produce (or absorb, in the case of reactive power) without damage that is caused by overheating.
  • Page 55 CGCM-DLR Unit Operation Chapter 3 Volts/Hertz Limit The Volts/Hertz limit acts to reduce the generator output voltage by an amount proportional to generator frequency. Generator output voltage reduction is done to help protect the generator from overheating and reduce the impact on the prime mover when adding a large load.
  • Page 56 Chapter 3 CGCM-DLR Unit Operation Over-excitation Limit The Over-excitation limit (OEL) operates in all modes except FCR. The CGCM-DLR unit senses and limits the field current to prevent field overheating. When the limit is reached, the limiter function overrides AVR, VAR, or Power Factor modes to limit field current to the preset level.
  • Page 57 CGCM-DLR Unit Operation Chapter 3 Three OEL current levels, high, medium, and low are defined for online operation as shown in Figure 33. The high and medium current levels can be maintained only for time periods you define. The generator can operate continuously at or below the low OEL current level.
  • Page 58 Chapter 3 CGCM-DLR Unit Operation Under-excitation Limit The Under-excitation limit (UEL) operates in all modes except FCR mode. UEL senses the leading VAR input of the generator and limits any further decrease in excitation to prevent loss of synchronization and the excessive end-iron heating during parallel operation.

  • Page 59: Protection Functions

    CGCM-DLR Unit Operation Chapter 3 Protection Functions The CGCM-DLR unit detects the fault conditions that are listed and described in the following section. Faults that are detected by the CGCM-DLR unit are communicated to the host Logix programmable controller. Fault flags are communicated in the Scheduled Read table.
  • Page 60 Chapter 3 CGCM-DLR Unit Operation Over-excitation Voltage (59F) (field over-voltage) When the field voltage rises above the level you specified for more than a set amount of time, a field over-voltage annunciation occurs. Once the field voltage drops below the threshold, the field over-voltage timer is reset. If this fault occurs, the CGCM-DLR unit shuts down excitation and sets tag OvrExcFlt = 1 in the Scheduled Read table.
  • Page 61 CGCM-DLR Unit Operation Chapter 3 Loss of Sensing (60FL) For three-wire and four-wire sensing, Loss of Sensing detection is based on the logical combination of several conditions. They include these conditions: 1. The average positive sequence voltage is greater than 8.8% of the AVR setpoint.
  • Page 62 Chapter 3 CGCM-DLR Unit Operation Loss of Excitation Power (PMG) (27) If voltage to the PMG excitation power inputs falls below 10V AC for approximately 400 ms or more, a Loss of Excitation power fault occurs. When single phase PMG is selected, the CGCM-DLR unit senses phases A and C for this function.
  • Page 63 CGCM-DLR Unit Operation Chapter 3 Over-frequency (81O) When generator frequency exceeds the over-frequency setpoint for a specified amount of time, a definite time over-frequency fault occurs. Once the frequency drops below the threshold, the over-frequency fault timer is reset. If this fault occurs, tag OvrFreqFlt = 1 in the Scheduled Read table.

  • Page 64: Synchronizing

    Chapter 3 CGCM-DLR Unit Operation When the ripple current at one of these frequencies exceeds the applicable user specified threshold, a timer is started. Once the time delay is exceeded, a rotating diode fault occurs. If the ripple current falls below the threshold (configured as percent of measured excitation current) before the timer expires, the timer is reset.
  • Page 65 CGCM-DLR Unit Operation Chapter 3 When synchronizing a system between systems with differing metering configurations, the synchronization configuration must account for any phase shift or voltage differences between the two systems. For example, when synchronizing a three-wire (delta) generator to four-wire (Wye) bus system, the synchronization configuration must account for the 30°...
  • Page 66 Chapter 3 CGCM-DLR Unit Operation • Single-phase The CGCM-DLR unit can synchronize where only one line-to-line input is available from the generator or bus. This scheme is the case for single-phase systems or in systems where only one phase has a transformer that is connected for synchronization purposes.
  • Page 67 CGCM-DLR Unit Operation Chapter 3 – Phase rotation (3-phase connection only): If the bus and generator are opposite in phase rotation, synchronization fails. The CGCM-DLR unit continually checks phase rotation match when synchronization is active. • Permissive Synchronization The host controller sets the PermissiveSyncEn tag to enable Permissive Synchronization mode.

    CGCM-DLR Unit Operation Chapter 3 Limit defines the maximum per unit load share error reported to the host controller. Rate defines the maximum change in the load share error per CGCM-DLR unit update cycle, expressed in percent of rated kilowatts per second. For example, if a change of load of 50% is required and the rate set for 10% per second, the change takes 5 seconds to complete.

  • Page 72 Chapter 3 CGCM-DLR Unit Operation If a loss of communication between redundant CGCM-DLR units occurs, the primary CGCM-DLR unit remains primary and the secondary CGCM-DLR unit switches to primary also. Because in this state both units are supplying current to the field, the host Logix programmable controller must be programmed to take corrective action when this condition occurs.
  • Page 73 CGCM-DLR Unit Operation Chapter 3 Once the host controller establishes primary and secondary CGCM-DLR unit roles, they remain in their respective modes indefinitely. You can force a transfer by disabling excitation on the primary unit. The disabling of excitation causes the secondary unit to sense a loss of tracking information, switch to Primary mode, and take over-excitation control.

  • Page 74: Watchdog Timer

    Chapter 3 CGCM-DLR Unit Operation The redundant tracking delay setting adjusts the delay of the tracking function to prevent the secondary CGCM-DLR unit output from being adjusted into an undesirable condition. For example, with AVR mode active in the primary CGCM-DLR unit, if the generator sensing VT fails open the excitation output goes to a full-on state.
