Provides guidance to owners and operators of electricity generation, transmission or distribution network assets, or gas distribution assets, which are required by statute to have a safety management system (SMS) that operates to safeguard members of the public or property of members of the public from safety-related risks arising from the presence or operation of these assets. The standard applies to all electricity transmission and electricity distribution assets in one or more systems with a total capacity equal to or greater than 10 MVA, and to all electricity generation assets in one or more systems with a total capacity equal to or greater than 10 MW. It also applies to all gas distribution assets in one or more systems, including all natural gas and LPG vapour distribution assets, that operate at a pressure equal to or less than 2000 kPa, and supply more than 10 terajoules of gas in any year, or have a flow design capacity equal to or greater than 10 gigajoules per hour. The total capacity for each asset type applies to each energy asset owner or operator irrespective of whether those assets are in one system or separate systems.

ISO 50045:2019

This document gives general technical guidelines for evaluating energy savings of thermal power plants before and/or after implementing energy performance improvement action(s) (EPIAs). It includes evaluation, unit component efficiency, indexes calculation, analyses and reporting.

This document is applicable to existing thermal power generating units (TPGUs), where fossil fuels (e.g. coal, oil, natural gas) are combusted to generate electricity only or to supply thermal energy with the additional production of electricity (i.e. combined cycle power plants).

NOTE A typical thermal power plant encompasses at least one TPGU. If there is more than one, the TPGUs can run independently.

Results obtained in accordance with this document can be used either to evaluate the potential of energy savings or to determine fulfilment of contract guarantees. They do not provide a basis for comparison of the energy savings between TPGUs.

This document does not prescribe performance tests or measurements for TPGU equipment components/systems, the sampling and analysis of the fuels used, substances added for control of emissions (e.g. halide, limestone) and by-products (e.g. ash, gypsum), and instruments to be employed, but it does specify parameters of interest in the determination of energy savings. Applicable procedures can be found in relevant documents (published or to be published).

ISO 37160:2020

Tue, 05 Nov 2024 23:09:52 +0000

This document specifies methods for measuring the quality of thermal power infrastructure (QTPI) during the operational phase and requirements for operations and management activities.

It is intended for use by electric power providers, including public utilities and independent power producers (hereinafter collectively referred to as power plant operators), as well as relevant stakeholders that intend to maintain and improve QTPI.

NOTE The selection and importance of evaluation indicators resulting from the implementation of this document can vary depending on the characteristics of the power plant operator.

ISO 18888:2017

Tue, 05 Nov 2024 22:11:05 +0000

ISO 18888:2017 specifies standard rules for preparing, conducting, evaluating and reporting thermal performance tests on combined cycle and cogeneration power plants driven by gas turbines for base and part load operation with or without supplementary firing.

ISO 18888:2017 is applicable to

– thermal performance tests for general information,

– thermal acceptance tests for determining the performance of the combined cycle plant in relation to a contractual guarantee, and

– comparative tests designed to check the performance differentials of the combined cycle and cogeneration power plants, for testing before and after modifications, upgrades or overhauls.

It can be used to determine the following thermal performance test goals and expected values, under specific operating and reference conditions within defined test boundaries:

– electrical power output;

– heat rate or thermal efficiency;

– process steam and/or district heat w/o generation of electrical power output by means of a steam turbine.

ISO 18888:2017 does not apply to individual equipment component testing, which is covered by corresponding standards.

It is not intended to be applied to the following test goals:

– environmental testing for example emissions, noise;

– vibration testing;

– operational testing;

– absolute or comparative performance of specific components of the combined cycle covered by dedicated standards (e.g. gas turbines).

ISA TR77.30.01-2015

Tue, 05 Nov 2024 20:20:04 +0000

Full Description

This technical report defines test procedures, data collection requirements and data analysis methods for determining and reporting the dynamic performance of control systems for boiler and turbine control systems on generating units with a rated capacity of 25 MW or greater or a boiler steam flow greater than 25 kg/s (200,000 lb/hr). This technical report covers aspects of dynamic plant operation including constant load operation, normal load ramping operation, grid regulation operation, and response to frequency upset, load runback, and load rundown operation.

The purpose of this technical report is to establish dynamic performance criteria for power plant control systems by specifying a consistent means of evaluating control system performance necessary to comply with contractual specifications and other dynamic performance requirements.

ISA RP77.60.02-2014

Tue, 05 Nov 2024 20:19:40 +0000

Full Description

This recommended practice is provided for the benefit of design engineers and, ultimately, plant operators. Use of this recommended practice will result in a more coherent and useful application of plant alarms for operations personnel. The goal of this recommended practice is to reduce alarm discrepancies, clutter, excessive noise levels, and information overload, but it is not intended for post-factum analysis of events.

This recommended practice will address the following alarm-related issues.

Functional grouping
Prioritization
Order and consistency
Colors
Formats and displays
Audio tone and pitch
Acknowledge, reset, and test functions
Nuisance alarms

These items are addressed both individually and with respect to their relationships with one another.

This recommended practice pertains to alarms displayed using lights or light boxes, but not software-based alarms (e.g., CRP-based alarms) and is intended to supplement the information provided by ISA-18.1-1979 (R2004), Annunciator Sequences and Specifications.

ISA 77.70.02-2014

Tue, 05 Nov 2024 20:19:06 +0000

Full Description

This standard covers the mechanical design, engineering, fabrication, installation, testing, and protection of fossil power plant instrumentation sensing and control lines. The boundaries of this standard span the process tap root valve to the instrument connection. This standard applies to all fluid media (liquid, gas, or vapor).

Purpose

This standard establishes the applicable installation requirements and limits of instrumentation sensing and control lines and their instruments in fossil power plants.

This standard addresses the requirements of maintaining the pressure boundary integrity of the instrumentation sensing line (in accordance with the appropriate parts of American National Standards Institute [ANSI] standards).

These subsystems include, but are not limited to, superheat temperature control and reheat temperature control. Specifically excluded from consideration are controls associated with fluidized-bed, stoker-fired furnace combustion units and mud drum desuperheaters.
