  • Page 12: Application

    The DSLC-2 control provides a safe automatic dead-bus closure function. Deadbus closing permission is granted to only one DSLC-2 or MSLC-2 control in the whole system, through locking techniques done over the communications network. This assures that a race condition will not cause two or more breakers to close simulta- neously on the dead bus.

  • Page 13: Load Control

    Load Control ≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ Load control begins at breaker closure when the load control function takes control of the DSLC-2 speed bias output directly from the synchronizer. The matching of synchronizer slip frequency to initial load (unload trip level) can result in a bumpless transfer to load control. On command, the adjustable ramp allows smooth, time- controlled loading into base load, isochronous load sharing or process control.

  • Page 14: Process Control

    The var/PF controller will limit the generators kvar output to the generator rated reactive power setpoint when connected to an infinite bus. A DSLC-2 must be in baseload or process control or a MSLC-2 must be in control. This will protect the generator when connected to an infinite source. This feature is not active when the DSLC-2 is in the load sharing mode (isolated).

    (lagging) reduces the voltage or an increasing capacitive load (leading) increases the voltage. The DSLC-2 in- cludes a droop setting for the voltage biasing signal. Woodward recommends that you always use a droop CT on the voltage regulator and set for around 3 % droop for best control.

    Droop Tracking When an active DSLC-2 is placed in the droop tracking mode it keeps the speed and voltage bias settings at their present values. This means that the kW and kvars will remain at their present values.

    Manual 37443A DSLC-2 - Digital Synchronizer and Load Control Droop/Isochronous Load Sharing On An Isolated Bus Droop/isochronous combines the first two modes. All generator sets in the system except one are operated in the droop mode. The one unit not in droop is operated in the isochronous mode. It is known as the swing machine. In this mode, the droop machines will run at the frequency of the isochronous unit.

  • Page 163: Isochronous Load Sharing On An Isolated Bus

    All DSLC-2 units are connected via Ethernet channel Network A. Load share is possible for all DSLC-2 units that are in the same segment. Any imbalance in load between units will cause a change to the regulating software in each unit. While each unit continues to run at isochronous speed, these changes force each machine to supply a proportional share of power to meet the total load demand on the system.

  • Page 164: Load Control Mode Switching

    In single unit operation, speed will decrease as load increases, as described above. In parallel with a bus, the generator is loaded by increasing the speed reference. The DSLC-2 control will provide the droop signal required for stability. When the “CB Aux” contact input is closed, the generator is paralleled to a bus, the load control operating mode contact inputs become effective.

  • Page 165: Soft Loading Into A Load Sharing System

    Soft Unloading From A Load Sharing Or A Base Loaded System The unload sequence is initiated by opening the “Load/Unload” contact. The DSLC-2 control then ramps the load down to zero at the preset rate. When the load reaches the unload trip level setpoint, the “Breaker Open” relay, terminal 47/48, is momentarily deactivated to initiate the opening of the generator breaker.

  • Page 166: Base Loading Against A Utility

    When the trip level is reached, the breaker open command relay is momen- tarily deactivated to separate the generator from the utility. When the “CB Aux” contacts open, the DSLC-2 con- trol goes into droop behavior and keeps the frequency on the initial state.

    Controlled By MSLC-2 Utility Mode A DSLC-2 only listen to a MSLC-2 when in load sharing mode. This means that the “CB Aux” and the “Load / Unload” inputs are closed. The DSLC-2 will display “Baseload” for the Load control mode (parameter 4603).

  • Page 169: Chapter 6. Var/Power Factor Control Description

    The Reactive load droop setting, on Menu 4 (parameter 5604), is = 0, then the biasing output remains on the last biasing level. The voltage regulator must have a droop CT installed with a 1 to 3 % droop ad- justment. Woodward always recommends to have a droop CT installed and active on the voltage regula- tor.

  • Page 171: Var Control

    Whether var control or power factor control is enabled, internally the var setpoint for the generator is restricted from +100 % to -10 % rated reactive power. When the DSLC-2 is operating in the base load mode, process mode or with an active MSLC-2 control, it will not allow the kvar output of the generator to increase above 100 % or below -10 % of the Generator rated reactive power (parameter 1758).

Var sharing adjusts the voltage regulators so that all genera- tors carry the same proportion of reactive load by balancing the kvar on all units. A Voltage reference setpoint, Menu 4 (parameter 5600) is provided to define the isolated operating voltage.

    Introduction ≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ The process control function of the DSLC-2 will control any process where the controlled parameter is deter- mined by the generator load and the controlled parameter can be monitored as an analog input signal (process in- put). The control compares the input signal to the process reference or the external load reference signal if it is used and adjusts the generator load to maintain the desired setpoint.

  • Page 175: Chapter 8. Network / System Description

    Segment connectors inform the DSLC-2s and MSLC-2s which generators and utilities are connected. Through the segmenting the DSLC-2 / MSLC-2 can recognize all the time with which other units they are inter- connected. So the DSLC-2s in the same segment are load share together or doing an independent load control.

    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 indication is the need for a segment breaker between segment 3 and 5, which does not exists.

    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 DSLC-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.

    (PLCs). It has become a de facto standard communications protocol in industry and is now the most commonly available means of connecting industrial electronic devices. The DSLC-2 / MSLC-2 supports a Mod- bus 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 exist on one Modbus RTU network, assuming that the serial interface is a RS-485.

    AC measurement data, switch states and various other information may be polled. According to the DSLC-2 / MSCL-2 Modbus addressing range, the visualization protocol can be reached on addresses starting at 450001. On this address range it is possible to do block reads from 1 up to 128 Modbus registers at a time.
