Standards

 

ASME PTC 18-2002, Hydraulic Turbines

and Pump - Turbines

This Code defines procedures for field

performance and acceptance testing of

hydraulic turbines and pump-turbines operating

with water in either the turbine or pump mode.

 

 

ASME PTC 29-2005, Speed Governing

Systems for Hydraulic Turbine

Generators Units

The objective of this Code is to provide uniform

test methods and procedures to determine the

performance and operational characteristics of

a hydraulic turbine speed governor. This Code

may be used to conduct factory acceptance

testing or to evaluate the current characteristics

of an installed speed governor. Not all of the

possible results that can be determined by

application of this Code need be part of every

test. Prior to testing, the parties to the test shall

agree whether the Code shall be used in whole

or in part to satisfy individual test objectives.

reaction turbine, storage pump or pump turbine. Determines

whether the contract guarantees have been fulfilled and deals

with the rules governing these tests as well as the methods of

computing the results and the content and style of the final

report. Replaces IEC 60198 (1966) and IEC 60607 (1978). "

"Deals with the definition and the characteristics of control systems. It is not limited to the actual controller tasks but also includes other tasks which may be assigned to a control

system, such as sequence control tasks, safety and provision

for the actuating energy. The following systems are included,

speed, power, opening, water level and flow control for all

turbine types; electronic, electrical and fluid power devices;

safety devices as well as start-up and shutdown devices. "

 

 

IEC 60545 Ed. 1.0 b:1976

"Guide for commissioning, operation and maintenance of hydraulic turbines"

"Establishes suitable procedures for commissioning, operating

and maintaining hydraulic turbines and associated equipment.

Applies to impulse and reaction turbines of all types, and

especially to large turbines directly coupled to electric

generators. Also applies to pump-turbines when operating as

turbines, and water conduits, gates, valves, drainage pumps,

cooling-water equipment, generators, etc., where they cannot

be separated from the turbine and its equipment. "

 

 

 

IEC 60609-1 Ed. 1.0 b:2004

 "Hydraulic turbines, storage pumps and pump-turbines - Cavitation pitting evaluation -

Part 1: Evaluation in reaction turbines, storage pumps and pump-turbines"

"Provides a basis for the formulation of guarantees applied to

cavitation pitting for reaction hydraulic turbines, storage pumps

and pump-turbines. It addresses the measurement and

evaluation of the amount of cavitation pitting on certain

specified machine components for given conditions, which are

defined in the contract by output, specific hydraulic energy (E),

speed, material, operation, etc. The cavitation-pitting

evaluation is based on the loss of material during a given time

and under accurately defined operating conditions. All wetted

surfaces are considered "

 

IEC 60609-2 Ed. 1.0 b:1997

 "Cavitation pitting evaluation in hydraulic turbines, storage pumps and pump-turbines - Part 2: Evaluation in Pelton turbines "

"This standard serves as a basis for the formulation of

guarantees on cavitation pitting on Pelton turbine runners. It

also provides a basis for the measurement and evaluation of

the amount of cavitation pitting on Pelton turbine runners of a

given turbine, which is defined in the contract by power,

specific hydraulic energy of machine (head), rotational speed,

material, operation etc. Guarantees which restrict the extent of

caviation pitting and drop erosion on Pelton turbies at the end

of an operating period specified in the contract are necessary

when the pitting is expected in all or in some operating

ranges."

  

IEC 61362 Ed. 1.0 b:1998

Guide to specification of hydraulic turbine control systems

 

 

IEC 62237 Ed. 1.0 b:2003

Live working - Insulating hoses with fittings for use with hydraulic tools and equipment

Is applicable to mobile insulating hoses with fittings used with

hydraulic tools and equipment for live working at nominal

voltages exceeding 1 kV r.m.s. at power frequency. Insulating

hoses with fittings are used to provide a connection between

the hydraulic tool and the pump which are at different

potentials. They are not considered as a fixed component of a

live working device (e.g. aerial device). They can be connected

and disconnected under negligible pressure. They can be

directly handled by the user.

US federal programmes and mandates for turbines

U.S. Department of Energy, National Energy Technology Laboratory "Coal and Power Systems: Turbines"
http://www.netl.doe.gov/technologies/coalpower/turbines/index.html

This site explores the Turbine Program of the U.S. Department of Energy's (DOE) Office of Fossil Energy (FE). It provides information about NETL's Turbine Program and its goals, current projects and solicitations, and performance targets of on-going projects.

U.S. Department of Energy, National Energy Technology Laboratory "Turbine Program: Enabling Near-Zero Emission Coal-Based Power Generation" (June 2005)
http://www.netl.doe.gov/technologies/coalpower/turbines/refshelf/brochures/Brochure%209-19-05.pdf

This document delineates today’s U.S. Department of Energy (DOE) Turbine Program being
implemented by the DOE National Energy Technology Laboratory (NETL). The Turbine Program
leverages the knowledge gained in making unprecedented advances in natural gas-fueled turbine
technology under the highly successful, predecessor Advanced Turbine Systems (ATS) Program.
This knowledge will be applied to support DOE efforts to develop and deploy near-zero emission
(including carbon dioxide) coal-based energy plants capable of producing both electricity and hydrogen.

U.S. Department of Energy, Office of Fossil Energy, "How Gas Turbine Power Plants Work"
http://fossil.energy.gov/programs/powersystems/turbines/turbines_howitworks.html

A simple cycle gas turbine can achieve energy conversion efficiencies ranging between 20 and 35 percent. With the higher temperatures achieved in the Energy Department's turbine program, future hydrogen and syngas fired gas turbine combined cycle plants are likely to achieve efficiencies of 60 percent or more. When waste heat is captured from these systems for heating or industrial purposes, the overall energy cycle efficiency could approach 80 percent.

U.S. Department of Energy, Office of Fossil Energy, "The Turbines of Tomorrow"
http://fossil.energy.gov/programs/powersystems/turbines/index.html

The Energy Department's Fossil Energy Program is developing key technologies that will enable advanced turbines to operate cleanly and efficiently when fueled with coal derived synthesis gas and hydrogen fuels. Developing this turbine technology is critical to the creation of near-zero emission power generation technologies. This will assist with the deployment of FutureGen plants that couple production of hydrogen and electricity from coal with sequestration of the carbon dioxide that is produced.
