This feature, when programmed, allows an operator to select one unit out of all the units on an isolated bus to function as the swing machine, and to change the operating swing machine while in operation. The other units on the bus then operate in a drooped or baseloaded mode. Frequency control can be armed or disarmed while connected to an isolated or infinite bus, however, when Armed, a unit will switch to Frequency control if the plant-to-utility tie breaker opens. When Disarmed, a unit will stay in a unit-load control mode when the plant-to-utility tie breaker opens. To use this feature, the program’s ‘Use Freq Arm/Disarm’ setting must be set to ‘Yes’, the Sync/Load Sharing mode cannot be programmed, and a discrete command must programmed. The Frequency Arm/Disarm mode can be selected from a programmed contact input, Function key, or Modbus command. When the programmed contact input is closed the unit’s Frequency control mode is Armed. When the programmed contact input is open the unit’s Frequency control mode is Disarmed. Depending on a unit’s size and running status, an operator may select which unit is designated as the plant frequency control unit should the plant-to-utility tie breaker open. Frequency control can be armed at any time, but it will only go into control when the generator breaker is closed and the utility tie breaker is open. CAUTION Only one unit at a time should have its’ Frequency control mode armed. If multiple units try to control plant frequency at the same time they may fight and cause system instability, with the potential of damage to the equipment due to overloading or reverse powering a machine.
If the program’s ‘Use Freq Arm/Disarm’ setting is set to ‘No’, Frequency control is always armed and the unit will go into Frequency control when the utility tie contact is open. If the program’s ‘Use Freq Arm/Disarm’ setting is set to ‘Yes’ then Frequency control must first be armed before the unit will switch into Frequency control when the utility tie contact is open and the generator breaker is closed.
Speed Control Dual Dynamics The Speed PID has two sets of dynamics: off-line and on-line. When a system has variable response times, due to changing system conditions, these dynamic variables allow the Speed PID to be tuned for optimal response. When the 505E is configured for a generator application, the utility tie and generator breakers determine which set of dynamics is used by the Speed PID. The speed PID’s off- line dynamics are selected when either the utility tie or generator breakers are open. The Speed PID’s on-line dynamics are selected if both breakers are closed (see Table 3-1).
