Manual 37444F MSLC-2 - Master Synchronizer and Load Control Chapter 1. General Information Document Overview ≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ This manual describes the Woodward MSLC-2 Master Synchronizer and Load Control.

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ The Woodward MSLC-2™ control is the direct successor of the former MSLC™ master synchronizer and load control. The MSLC-2™ is a microprocessor-based overall plant load control designed for use in a system with Woodward DSLC-2 (“Digital Synchronizer and Load Control”) controls on each gen- erator to provide utility synchronizing, paralleling, loading and unloading of a three-phase generating system.
MSLC-2 issues a breaker open command to separate the utility from the local bus. The ramp pause switch can be used to stop the utility unload at any point. The maximum load that the MSLC-2 can tell the individual generators to carry is their rated loads. So, in the event that the plant load is greater than the capacity of the operating generators, the utility unload will stop when 100% rated load is reached on each of the operating generators.
100% or 0%, the control will maintain that load reference until process control is established. The MSLC-2 is not capable of overloading or reverse powering the generators in an attempt to meet the process reference. The high and low limit switches mentioned above can be used to indicate that either too many or too few generators are online to maintain the process within its limits.
DSLC-2 / MSLC-2 Systems ≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ The network addressing of the DSLC-2 / MSLC-2 allows up to 32 DSLC-2s and 16 MSLC-2s in an ap- plication. A DSLC-2 and MSLC-2 application can handle 8 segments. Discrete inputs inform the DSLC- 2s and MSLC-2s which segments each generator and utilities are operating on. If a MSLC-2 receives a discrete input to activate segment 1 and 2, it will share this information with all controls over the Ether- net bus.

Dead Bus Closure – Multiple Units When a dead bus is detected and dead bus closing mode is “Enabled”, the MSLC-2 is doing a security check before issuing a breaker closure command. This security is required to prevent two or more units from closing their breakers at the same time.
If there is a breaker (GCB and/or MCB) closed in the own segment and/or (own segment+1), then the alarm “Deadbus closure mismatch” is set and the MSLC-2 will not close to a deadbus. The alarm “Deadbus closure mismatch” (parameter 4620) shows the deadbus plausibility in ToolKit Menu 8. Addi- tional, a Relay output: Alarm1, Alarm2 or Alarm3 can be assigned within ID 7598 in ToolKit Menu 0.
DSLC-2 controls over the Ethernet network. The MSLC-2 will continue this process until the difference between System B and System A voltage is within a specified window. The automatic voltage matching function may be enabled or disabled with a configuration setpoint.
This is important when you have multiple utilities attempting to close to a dead bus. The MSLC-2 that receives the dead bus token will not pass the dead bus token until it receives an alarm. So having 1 or 2 close attempts is preferred in a multiple utility application.
With reaching the MSLC-2 setpoint, the DSLC-2 disables the ramp and channels the setpoint through to the load PID. The behavior with the kvar setpoint is the same as long kvar—or PF—control is done over the MSLC-2 interchange point (Kvar Import/Export Control).

MSLC-2. The MSLC-2 can synchronize multiple DSLC-2s to the utility. Once the utility breaker is closed, the MSLC-2 must be placed in a load control mode. These are base load, import/export, process control or utility unload. MSLC-2s in the tie-breaker mode will synchronize and close the tie-breaker to connect different bus segments but will not have any load control capabilities.
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ Ramping Between Modes Whenever the mode of load control is changed, the MSLC-2 will ramp at a user chosen rate until it is within 5% of its new reference. Then, it will begin dynamic control. This provides smooth (bumpless) transitions between all modes.
MSLC-2 - Master Synchronizer and Load Control supplying power to the utility, the MSLC-2 will lower the system load setpoint to obtain a zero power transfer condition. If the local plant is initially operating at some import level, absorbing power from the utility, the MSLC-2 will raise the system load setpoint to obtain a zero power transfer condition.
It is important to note that, as with the real load functions, the var/PF control in the MSLC-2 controls only those DSLC-2 controls which are in isochronous load sharing. Any DSLC-2 controls which are in base load mode will control the reactive power on their associated generators in accordance with their own internal reference and chosen mode of var/PF control.
Introduction ≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ The process control function of the MSLC-2 will control any process where the controlled parameter is determined by the load on the local generators and the controlled parameter can be monitored as an analog input signal (process input). The control compares the input signal to the process reference set- point, or the remote reference if used and adjusts the local generator loading to maintain the desired setpoint.

Manual 37444F MSLC-2 - Master Synchronizer and Load Control displayed according to the percentage value. Therefore the scaling of the percentage value is to make with according engineering units (parameter 7732, parameter 7733 and parameter 7734). The units are then displayed in field parameter 7726 and in field parameter 7727 in Menu 6 or the Homepage.
The MSLC-2s can be configured to utility breaker mode or to tie-breaker mode. In each case it is only allowed to have one MSLC-2 in one segment running as master control. A MSLC-2 gets a master con- trol when base load control, export/import control or process control is activated. If multiple MSLC-2s are in the same segment, the control with the lowest device number will be master.
In some applications there is no segmenting to make because the common busbar of DSLC-2 and MSLC-2 cannot be separated. In this case in Menu 5, Basic segment number (parameter 4544) is con- figured to 1 at each unit. The Device number (parameter 1702) needs still to be different because it de- termines the network addressing.
Manual 37444F MSLC-2 - Master Synchronizer and Load Control Figure 8-5: Isolated / utility parallel operation with multiple generator, tie-breaker and generator group breaker Figure 8-5 shows an application with 2 utility feeder breakers, 2 load segments and 2 generator group breakers.
Special Function - Synchronizing the last breaker in a ring structure For the case the last tie breaker shall be closed in a ring structure the respectively MSLC-2 synchronizes the breaker without guiding voltage and frequency. But the tolerances for voltage and phase angle must be extended.
A main rule in the segmenting is that segment numbers have to follow a line without branches. At next are shown some application examples which are not covered by the DSLC-2 / MSLC-2 system. The application in Figure 8-7 and Figure 8-8 shows how the segment number line can branch. Another indi- cation is the need for a segment breaker between segment 3 and 5, which does not exists.

Manual 37444F MSLC-2 - Master Synchronizer and Load Control Changing a device in a running system First it is to check whether there is not yet a "Missing member" alarm active on the Ethernet network. If this alarm is active the reason for this is to clarify first. Otherwise the system update procedure would fade out this alarm situation.
It is important to know that the load share and load-dependent start/stop functionality is subject to a multi-master principle. This means that there is no dedicated master and slave function. Each MSLC-2 decides for itself how it has to behave. The benefit is that there is no master control, which may cause a complete loss of this functionality in case it fails.
The DSLC- 2 / MSLC-2 support a Modbus RTU Slave module. This means that a Master node needs to poll the slave node. Modbus RTU can also be multi-dropped, or in other words, multiple Slave devices can ex- ist on one Modbus RTU network, assuming that the serial interface is a RS-485.
Manual 37444F MSLC-2 - Master Synchronizer and Load Control Visualization The visualization over Modbus is provided in a very fast data protocol where important system data like alarm states, AC measurement data, switch states and various other information may be polled.
