If the 505E is programmed to control unit load using turbine valve positions, the 505E calculates load based on the valve positions at the time the generator breaker is closed. The valve positions at this point are considered to be zero load. In a typical application, where inlet and exhaust pressures are at rated levels when the generator breaker is closed, this zero load calculation allows unit load to be accurately sensed and controlled. Speed Setpoint The Speed PID’s setpoint may be adjusted from the 505E keypad, external contacts, Modbus commands, or through a 4–20 mA analog input. A specific setpoint setting can also be directly entered through the 505E keypad or Modbus communications. The Cascade PID also directly controls this setpoint when it is used. The speed setpoint range must be defined in the program mode. Program settings ‘Min Governor Speed Setpoint’ and ‘Max Governor Speed Setpoint’ define the normal operating speed range of the turbine. The speed setpoint cannot be raised above ‘Max Governor Speed Setpoint’ setting unless an Overspeed Test is performed. Once the speed setpoint is taken above the ‘Min Governor Speed Setpoint’ setting, it cannot be varied below this setting again unless the Idle/Rated ramp-to-Idle command is selected or a Controlled Stop is selected.

Once turbine speed is equal to or greater than the ‘Min Governor Speed Setpoint’ setting, the speed setpoint may be adjusted through discrete raise and lower commands. When a raise or lower speed command is issued, the setpoint moves at the programmed ‘Speed Setpoint Slow Rate’. If a speed raise / lower command is selected for longer than three seconds, the speed setpoint will then move at a faster rate which is three times the speed setpoint slow rate. The speed setpoint slow rate, fast rate delay, and fast rate can all be adjusted in the Service mode. The shortest length of time a setpoint will move for an accepted raise or lower command is 120 milliseconds (240 milliseconds for a Modbus command). If the speed setpoint rate is programmed for 10 rpm/sec, the smallest increment it will move is 1.2 rpm (2.4 rpm for Modbus). The speed setpoint may be set to a specific level, by directly entering a setpoint value through the 505E keypad or Modbus communications. To enter a specific setpoint from the 505E keypad, press the SPEED key to view the speed control screen, press the ENTER key, enter the setpoint level desired, then press the ENTER key again. If a valid number was entered, the setting will be accepted and the Speed setpoint will ramp to the “entered” setpoint level. If an invalid number is “entered” the setting will not be accepted and the 505E’s screen will momentarily display a value out-of-range message. After a valid setpoint value is entered and accepted, the setpoint will ramp at the speed setpoint slow rate (defaulted setting) to the newly entered setpoint value. The rate that the setpoint ramps at when a specific value is entered may be changed from its defaulted value by changing the ‘Entered’ rate setting under the Service mode’s “Speed Control Settings” header.
