Common Industry Problems

9

Labour Productivity:• Labour costs• Increased levels of management• Skill shortages,• Resistance to change!• De-engineering of organisations, reducing innovationCapital Delivery:• (over) Regulation, industry unbundling and privatisation• Design standards & procurement options• We need to do more with less!

Bushfires and other disasters

• Cost of Feb 2009 Victorian Bushfires 2009 -$4.4 Billion, 173 lives - source “The Age”, 1 August 2010

• Powerlines caused the worst of these fires –source VBRC

• Root cause of many of these power-line failures was poor design, poorly executed maintenance and monitoring – source Terry Krieg

• Conservative and $ driven utilities• Simple, proven technology available

Generation Y

• ‘Millennials’: born 1982 – 2004• Confident and tolerant – “Gen-me”• Sense of entitlement, ambitious, civic minded• Grew up with computers – connected world• Information hungry, social networking,

decision makers• They will be soon running the power grid!

Study Committee B3 Mission • To facilitate and promote the progress of engineering• International exchange of information and knowledge of

substations. • Add value to this information and knowledge by:

• Synthesizing state-of-the-art practices and • Developing recommendations and providing best practice.

Including:

• Design, construction, maintenance and ongoing management • Technical, economic, environmental and social aspects for

stakeholders• Increasing reliability and availability, cost effectiveness, reduced

environmental impact, effective asset management.• Requires effective relationships with other SC’s

SC B3 – Study Subjects2016PS 1: Advancements in substation technology

GIS and GIL developments including new DC technologies Integrating Non-Conventional instrument transformers Integrating new materials and new technologies into substations

PS 2: Developments and new thinking in substation design Integrating IEC 61850 into existing substations Maximising substation availability Modular, pre-fabricated, fast deployment and off-shore substation solutions Adaption of substations to meet emerging grid requirements.

PS 3: Evolution in Substation Management Risk quantification and optimised asset decision making, substation economics,

maintenance management Customer and stakeholder interaction with design and life cycle management Substation asset performance, residual life, health and condition metrics Substation auxiliary and ancillary systems Knowledge management, design methodologies and training

Grid Trends - Substations

• Improved high voltage plant design and methods

• Ultra high voltage (1200kV in India)• Smart Grids and even smarter substations• Higher use of IEC 61850 Station & Process

(compatible with OLCM technologies)

24

Grid Trends - Substations

• Increasing stakeholder and customer awareness and influence in design

• More awareness of severe weather conditions – (climate change?)

25

Grid Trends - Substations

• The use of robotics in substations• More risk management – coupled with

awareness of Asset Management – PAS 55 and ISO 55000.– On-line technologies continue to develop

26

Grid Trends – Lines

• Improvements in plant technology• Developments in monitoring have been

slower (particularly Distribution systems)• Bushfire investigations highlighted the

importance of inspection and monitoring• Utilities are good at reactionary responses to

faults – more efficient but largely unchanged• Technologies are available to pre-empt issues.

27

On-Line Monitoring

• Can be used for Lines and Substations• Can reduce the risk of unplanned failures• Detecting problems before they become faults• Provides information on condition when

maintenance frequencies reduced• Now a mature technology• There are still non-believers!• February 2009 Bushfires, April 2013…

28

Obtaining the Benefits

• Aim for highest risk reduction but be realistic!• Use field proven technologies• Deal with knowledgeable “partners” / suppliers• Embed the monitoring into a risk based, asset

management approach• Invest in training for your people• Consider your IT systems – non-vendor specific• Forget the research projects!

29

Taking hold of the future?

• Have a long term strategy– Have a reason for collecting data– Information for asset decision making.

• Monitoring system features or sensors– Look for quality sensors, trend-able and accurate

• IT systems– Web interface for easy access– Make the technology available to those needing

• KISS

30

The Future Grid

• Primary plant enclosed, “maintenance free”.• Digital substations• Unmanned, automated, robotic patrols• Condition sensors supplied with primary plant • Sensors on lines providing information to

crews prior to failure• Expert analysis systems deployed• Mobile device interfaces

31

Conclusions• On line monitoring has come a long way• We need to learn to trust and use it!• New technologies are available and evolving• For condition: focus on simplicity and making

decision-making easier • Turn data to information to knowledge• Use the work of CIGRE and IEEE so we don’t

need to reinvent the wheel
