Because the 505E’s Speed PID and setpoint are used to control turbine speed and a second parameter, this second parameter (unit load) is normalized to allow all three terms (speed, setpoint, unit load) to be summed together within the PID summing junction. This normalization is based on a percentage of rated speed and creates a direct relationship between unit load and the Speed PID’s setpoint. Once unit load (0-100%) is represented as a percent of rated speed, the speed setpoint can be varied by this percent, above rated speed, to increase load from 0-100% when paralleled to the utility. Unit load is converted to a percentage of rated speed as shown in the following example calculation: DROOP % x (gen load or valve positions-%) x Rated Speed = Setpoint change in RPM Example: 5% x 100% x 3600 rpm = 180 rpm For this example when paralleled to a utility bus, the speed setpoint can be adjusted from 3600 rpm to 3780 rpm to vary unit load from 0 to 100%. The ‘Maximum Governor Speed’ setting should be programmed as 3780 rpm. Droop feedback allows the Speed PID to control unit load (generator power or HP & LP valve positions) once it is paralleled with a utility bus or other generating systems which do not have droop or loadsharing capability. When a turbine generator set is paralleled with a utility bus, the utility determines the unit frequency/speed, thus the 505E must control another parameter. The 505E senses unit load through the turbine HP and LP valve positions or an analog input from a watt transducer sensing generator load. HP and LP valve positions are sensed by their respective 0-100% actuator drive currents. Thus the calibration of drive current to actual valve position is very critical, and should be adjusted as close as possible

It is recommended that a Woodward Real Power Sensor or equivalent watt transducer be used to sense generator load and feed it back to the 505E’s kW input for kW droop control. However, if kW droop is not used or programmed, the 505E uses a calculated load value based off of turbine’s HP and LP valve positions when paralleled with an infinite bus. If the kW input signal fails while controlling generator load the 505E will issue an alarm and revert to its internal calculated load value. NOTE When using one of the Ratio/limiter’s decoupled modes it is recommended that kW droop not be used. Since unit power is effected by the position of both valves, using kW droop would reduce the desired decoupling action. To configure the 505E for generator load control when paralleled to a infinite bus, program the ‘kW DROOP’ setting to ‘YES’, and program the 505E to accept an analog input from a Watt transducer sensing generator load. To configure the 505E for turbine valve position control when paralleled to an infinite bus, program the KW DROOP setting to ‘NO’. The Speed PID’s droop percentage, (generator load or turbine valve positions) cannot be set greater that 10%, and is typically set at 5%.
