This Code applies to speed governors used on conventional, constant-speed hydraulic turbines. This Code is applicable to electronic-hydraulic and mechanical-hydraulic speed governors. These governors are commonly used to control reaction and impulse-type-hydraulic turbines (fixed or variable geometry) and pump turbines operating in generation mode.This Code specifies procedures for conducting tests to determine the following performance characteristics of hydraulic turbine speed governors:(a) droop:(1) permanent,(2) temporary;(b) deadband and deadtime:(1) speed,(2) position,(3) power;(c) stability index:(1) governing speedband,(2) governing powerband;(d) step response;(e) gain:(1) proportional gain,(2) integral gain,(3) derivative gain;(f) setpoint adjustment:(1) range of adjustment,(2) ramp rate.This Code also establishes the rules and procedures for the conduct of tests to determine the following operational characteristics of hydraulic turbine speed governors:(a) gate/blade relationship (dual regulated reaction turbines),(b) needle/deflector relationship (impulse turbines),(c) full-rate servomotor timing and cushion time.
