IEEE Standard 1159-1995 The Revised PQ
MonitoringStandard
- Randy Collins
- Chair, 1159 Working Group
- IEEE Power Engineering Society Winter Meeting
- New York
- January 28, 2002
2
Benchmark Document
- Monitoring of Electric Power Quality of single
and polyphase systems. - Descriptions of phenomena.
- Definitions of nominal and deviations from
nominal. - Recommendations for measurement techniques,
application techniques, and interpretation of
monitoring results.
3
Purpose
- The purpose of 1159-1995 is to direct user in the
proper monitoring and data interpretation of
electromagnetic phenomena that cause power
quality problems.
4
Purpose contd
- Defines power quality phenomena to facilitate
communication within the power quality community. - Forms the consensus opinion for safe and
acceptable methods for monitoring and
interpreting results. - Tutorial on power system disturbances and common
causes.
5
The next 1159
- At a minimum, 1159 needs to be updated and
include links to the forthcoming 1159.1 and .3
works. - What do we want the final product to look like?
6
Some ideas
- Ch. 1. Overview
- Expand and include information about why would
you want to measure for power quality? - Ch. 2. References
- Revise and update
7
Ch. 3 Definitions
- Terms used in this recommended practice
- Avoided terms
- Abbreviations and acronyms
- Expand with the former P1433 information
- Pull definitions from .1 and .3 documents
- Can we use and define terms not used in the
document? - Would this be difficult to ballot?
8
Ch. 4 Power Quality Phenomena
- Electromagnetic compatibility
- General classification of phenomena
- Detailed descriptions of phenomena
- Table 2 is probably the most widely used part of
the Standard. - Update the graphs.
- Expand the explanations.
9
Ch. 5 Monitoring Objectives
- Need for monitoring PQ
- Equipment tolerances and effects of disturbances
on equipment - Equipment types
- Effect on equipment by phenomena type
10
Ch. 6 Measurement instruments
- AC voltage and current measurements
- Voltage and current considerations
- Monitoring instruments
- Instrument power
- Revise and update.
- Incorporate some 1159. 1 information.
11
Ch. 7 Application techniques
- Safety
- Monitoring location
- Equipment connection
- Monitoring thresholds
- Monitoring period
12
Ch. 8 Interpreting monitoring results
- Interpreting data summaries
- Critical data extraction
- Interpreting critical events
- Verifying data interpretation
- Expand this to include data reduction and
presentation info. - How do you present multi-dimensional info on a
2-dimensional CBEMA/ITIC/SEMI curve?
13
Additional topics
- Sort of a case study section, except organize
it by equipment categories. - What to monitor and look for, what you dont need
to monitor for when investigating problems with
common equipment - ASDs, PLCs, Switching power supplies,
relays/contactors, lighting, etc.
14
Annexes
- Annex A Calibration and self testing
(informative) - Keep this or not?
- Annex B Bibliography (informative)
- Keep this and update/expand.
- New Annexes
- Technical summaries of the .1 and .3 documents.
15
Todays objectives
- Establish scope, purpose and other items required
for the PAR. - Determine a working outline and chapters
- Assign chapter chairs
16
Proposed Organization
- Ch. 1 and 2 Intro material
- Ch. 3 Defns
- Ch. 4 Phenomena
- Ch. 5 Objectives
- Ch. 6 Instruments
- Ch. 7 Applications
- Ch. 8 Interpretation and Statistical Analysis
- Ch. 9 Examples of using the standard in the
field - Annexes
- A Calib. and Self-Testing
- B Tech Summaries of 1159.1 and 1159.3
- C Bibliography
