Synchronization Status Messages • Disabled—The Synchronizing Input is disabled and will have no effect on the Speed setpoint. • Enabled—The Synchronizing Input has been enabled. • In Control—The Synchronizing Input is biasing the Speed setpoint. • Inhibited—The Synchronizing Input is inhibited and cannot be enabled. Input signal is failed, both the utility tie and generator breakers are closed, the turbine is shut down, a controlled shutdown is being performed, or synchronizing control is not programmed. Synchronizing / Loadsharing A Woodward Digital Synchronizer & Load Control (DSLC) is used with a 505E to allow automatic generator synchronization to a bus and the sharing of load with other units (using DSLCs on the same bus). The Woodward DSLC is a microprocessor based generator load control designed for use on three-phase AC generators with Woodward speed controls and automatic voltage regulators. A DSLC with VAR/Power Factor control, allows all units with DSLCs to reactive load share as well as real power load share. The DSLC senses unit load through generator PTs and CTs and system load through the DSLC LON network (a combination of all units on the network). The DSLC uses a digital Echelon Network (LON) to communicate with other DSLCs on the same bus. When used as a synchronizer and load control, the DSLC performs automatic synchronization and controls unit load based on an internal base-load setting, a system average load setting, a process loop’s control setting, or a Master Synchronizer & Load Control’s (MSLC) demand setting. After synchronization, unit load can be controlled by the DSLC through the Sync/Load Share input or by the 505E’s internal speed/load setpoint.
The Utility Tie Breaker Contact is used to select unit load control through the DSLC or through the 505E’s internal load setpoint. When the 505E’s internal load control is selected (utility tie contact closed), the Speed PID setpoint is used to control unit load. Optionally the Cascade or Auxiliary control modes may be used to set unit load based on another system parameter. The DSLC interfaces to the 505E via its Speed Bias signal. To configure the 505E to utilize a DSLC for generator synchronizing and load sharing, program the ‘Sync/Load Share input’ function to the ‘Analog Input #6’ setting and program the ‘Sync/Ld Share Enable’ function to a ‘Contact Input #X’ setting. Analog Input #6 is isolated, and the only input directly compatible with the DSLC’s output signal. The ‘Sync/Ld Share input’ function has preset range and gain settings that are tunable only in the Service mode (See Volume 2). Thus the 4 mA and 20 mA Program Mode settings for the Synchronizing input are irrelevant and are not used by the function’s operation. A combination of the Utility Tie Breaker contact, Generator Breaker contact, and Sync/Ld Share Enable contact define the state of the 505E’s synchronizing and loadsharing operating modes (See Table 3-2).
