3.1.2 hydraulic machine hydraulic impulse and reaction turbines, storage pumps and pump-turbines [SOURCE: IEC TR 61 364:1 999, 3.1 ] 3.1.3 turbine machine for transforming hydraulic energy into mechanical energy Note 1 to entry: The term turbine includes a pump-turbine functioning as a turbine. Note 2 to entry: The term turbine does not include the inlet or outlet valves nor the associated generator or governor. [SOURCE: IEC TR 61 364:1 999, 4.1 , modified – Addition of Note 1 to entry.] 3.1.4 pump machine for transforming mechanical energy into hydraulic energy in order to store water that will be used later on to produce electric energy Note 1 to entry: The term pump includes a storage pump and a pump-turbine functioning as a pump. Note 2 to entry: The term pump does not include the inlet or outlet valves nor the associated motor. [SOURCE: IEC TR 61 364:1 999, 4.1 , modified – Replacement of “storage pump” with “pump” in the main term, and addition of Note 1 to entry.] 3.1.5 starting device starting equipment for a motor-generator or motor EXAMPLE 1 pony motor EXAMPLE 2 starting turbine EXAMPLE 3 frequency converter EXAMPLE 4 hydraulic torque converter EXAMPLE 5 back to back Note 1 to entry: Each example is representing a different method to start the hydraulic machine functioning as a pump. 3.1.6 opening device guide vanes or the turbine needle of impulse turbines and its driving components (governing systems) 3.1.7 electrical machine generators and motor-generators of synchronous type including the excitation equipment as well as of the asynchronous type
4) Detailed sequential diagrams, illustrating ordinary changes from one mode of operation to another (generating, pumping, synchronous condenser operation, standby) as well as actions due to various electrical or mechanical faults. 5) Guide vane opening (or needle opening of impulse turbines) for no-load, starting and cavitation limits, as functions of head and tailwater levels also, where appropriate, runner blade or deflector position. 6) Transient calculations (model presentation, input data, design criteria/admissible value, load cases and descriptions of maximum and minimum values for pressure, speed, flow, safety margin, references), depending on the contract. NOTE 1 Closing and opening times of main valve sealings are considered. 7) Governor and servomotor characteristics (e.g. relationship between guide vane angle and servomotor stroke, cam relationship if applicable). 8) If applicable, description of the water-depression-system or de-watering and refilling system of the runner, data for compressed air tanks (including capacity of air tanks, control pressure, etc.), compressors, valves, automatic control devices (both for de-watering system and air leakage supplement system), maximum and minimum water level in the draft tube, etc. 9) Adjustment of overspeed protection device, information of set value (shutdown value). 1 0) If applicable, description of the coupling type between the hydraulic machine shaft and motor-generator shaft and of the synchronizing arrangement. 1 1 ) Characteristics of the fluids for the governing system. Filter specifications and information on purification frequency and method. 1 2) Control and servo systems. Description of type and control system of the main valve, the distributor and the movable blade of the runner (as applicable) as well as closing and opening laws for the main valve, the guide vanes and runner blades. 1 3) Maximum steady state runaway speed and maximum transient speed and pressure variations at some specific operating heads (maximum/minimum/rated water head).
