  23. TRANSMISSION SYSTEM PLANNING

  24. PLANNING – TABLE OF CONTENTS Definition General background and observations Evolution of the reliability level and strategic role Major design principles Design criteria Two major system components Four major planning activities Plans Expertise 1 2 3 4 5 6 7 8 9

  25. DEFINITION 1 • Planning • Determine specific objectives • Means to reach them within prescribed deadlines • Organize based on a plan • Therefore, planning at Hydro-Québec means: • Organizing a structured and integrated approach • Taking needs into account • Identifying optimal solutions • Ensuring consistency of development • global, long-term vision of system evolution

  26. INTEGRATED SYSTEM PLANNING (1) 1 • Long-term view • Global vision of challenges, problems and actions to be implemented • Consistency for entire system • Needs based on available and predictable information • Assessment of different scenarios to ultimately determine the optimal scenario

  27. INTEGRATED SYSTEM PLANNING (2) 1 MAIN CONSIDERATIONS • Distributor’s needs for local load • Requests from customers (connections to grid, point-to-point service) • Long-term operability • Technological innovation • Quality improvement • Standards and regulations • System control • Telecommunications 1 2 3 4 5 6 7 8

  28. OBSERVATIONS 2 • The system has distinctive features • Transmission assets make up an integrated whole and their interaction is necessary to the operation and proper functioning of the system • The system must have enough transmission equipment to meet all needs (no planned congestion) • The planning approach must be structured and integrated

  29. EVOLUTION OF THE RELIABILITY LEVEL 3 • The performance requirements initially used to design the system were not as demanding as they are today • The years between 1965 and 1989 were marked by several partial and major outages • Hydro-Québec then invested to improve service continuity and set out to become a full member of the Northeast Power Coordinating Council (NPCC) • Today, Hydro-Québec TransÉnergie boasts a very robust system (no blackout since 1989)

  30. MAJOR SYSTEM DESIGN PRINCIPLES (1) 4 • The context, constraints, observations, evolution in customer needs, etc. have led Hydro-Québec to develop design principles based on reliability • Based on the electrical integrity of the system PRINCIPLE 1 Service continuity must be ensured following the events most likely to occur on the system. PRINCIPLE 2 Measures must be in place to reasonably prevent a blackout after an exceptional event. PRINCIPLE 3 The system’s strategic equipment must not be damaged in the event of a blackout, to ensure that the system can always be restored. • Implementation of special protection systems based on the principle of successive lines of defence

  31. MAJOR SYSTEM DESIGN PRINCIPLES (2) 4 EVENTS INCREASING IN SEVERITY SECOND LINE OF DEFENCE FIRST LINE OF DEFENCE THIRD LINE OF DEFENCE ELECTRICAL INTEGRITY OF THE SYSTEM PRINCIPLE 1 PRINCIPLE 2 PRINCIPLE 3 EVENT FREQUENCY FREQUENT VERY RARE EXCEPTIONAL OBJECTIVES SERVICE CONTINUITY SYSTEM INTEGRITY EQUIPMENT SAFETY MEANS IN PLACE • Intrinsic robustness of the system • Equipment’s major features • Special protection systems • Special operating procedures • Special features of equipment • Special protection systems • Restoration • Blackstart capability • Internal emergency plan RESULTS NO LOSS OF LOAD POSSIBILITY OF PARTIAL OUTAGE WITH QUICK RESTORATION RISK OF BLACKOUT WITH QUICK RESTORATION

  32. MAIN SYSTEM CRITERIA (1) 5 DESIGN CRITERIA IDENTIFY EVENTS FOR WHICH THE SYSTEM MUST MEET AN ACCEPTABLE PERFORMANCE LEVEL BASIC CRITERIA (SYSTEM ROBUSTNESS, NPCC, NERC) • The system must remain stable during and after the most severe of basic events without loss of load and without using special protection systems • Examples of basic events • A three-phase fault on any element and normal trip-out of the element • Simultaneous single-phase faults on each circuit of a double-circuit line • Circuit-breaker fault • Loss of both poles of a direct-current bipolar facility

  33. MAIN SYSTEM CRITERIA (2) 5 COMPLEMENTARY CRITERIA (HQT-SPECIFIC) • The system must remain stable during and after the most severe of the complementary events (some exceptions apply) • Examples of complementary events • Single-phase fault with trip-out of the faulty line and another parallel line • Single-phase fault with trip-out of the line and bypass of series capacitor bank on a parallel line

  34. MAIN SYSTEM CRITERIA (3) 5 EXCEPTIONAL EVENTS (NPCC, NERC REQUIREMENTS) • NPCC and NERC require that these events be studied to assess system performance and identify remedial measures • According to Hydro-Québec TransÉnergie’s criteria, the system must remain stable under certain circumstances • Examples of exceptional events • Total loss of a generating station • Loss of all the lines exiting a substation • Loss of a major load centre

  35. REGIONAL SYSTEM CRITERIA 5 GENERAL PRINCIPLES • Equipment capacity adequate in normal mode (N) and during the unavailability of one piece of equipment (N-1) • Supply continuity during simple events; size and duration of load losses limited during more significant events • New 65 MVA or higher substations are supplied by more than one circuit • Voltage levels are maintained within normal ranges • Equipment capacity is adequate to support the system’s short-circuit levels

  36. TWO MAJOR COMPONENTS OF THE SYSTEM 6 THE MAJOR DESIGN PRINCIPLES ARE APPLIED TO THE SYSTEM’S TWO MAJOR COMPONENTS: • Main transmission system (mainly 735 kV and 315 kV) • Transmission system expansion • New hydroelectric and wind power generation • Reliability preservation, voltage control and compliance to design criteria; long-term operability • Transmission system interconnections • Regional systems • Impact of connecting new wind farms on system topology • Overloaded satellite substations, growth in energy requirements • Transformer capability additions • New regional infrastructure • Interconnections in regional systems

  37. FOUR MAJOR PLANNING ACTIVITIES 7 ESTABLISH DESIGN CRITERIA FOR THE SYSTEM AND TECHNICAL CHARACTERISTICS FOR THE EQUIPMENT DESIGN THE SYSTEM DESIGN EQUIPMENT TAKING TRANSIENTS (LIGHTNING, SWITCHING IMPULSES, ETC.) INTO ACCOUNT DEVELOP PROJECTS BASED ON CUSTOMERS’ NEEDS 1 2 3 4

  38. PLANS 8 STRATEGIC PLAN 2009–2013 The strategic plan defines the company’s major objectives, taking into account the shareholder (Québec government) and senior management’s objectives

  39. HYDRO-QUÉBEC TRANSÉNERGIE’S BUSINESS PLAN 8 1 ENSURE THE QUALITY OF POWER TRANSMISSION SERVICE 1 Ensure long-term operability of facilities through targeted investments STRATEGY 2 Ensure system reliability and availability 2 INCREASE TRANSMISSION SYSTEM CAPACITY TO MEET CUSTOMER NEEDS 1 Invest in response to growing needs STRATEGY 2 Increase interconnection transfer capability 3 FURTHER ENHANCE THE DIVISION’S PERFORMANCE 1 Continue to improve performance 2 Optimize investments in a context of strong growth STRATEGY 3 Base innovation efforts on four promising avenues 4 Maintain expertise and develop employees’ skills

  40. EVOLUTION PLANS 8 REGIONAL EVOLUTION PLANS • Extensive knowledge of the regional systems • Anticipate impact of growth and aging of equipment • Set long-term objectives (voltage levels, main equipment, topology) • Consistency of activities throughout entire system • Regional systems divided into smaller or larger entities according to needs • Feedback on criteria and processes MAIN SYSTEM PLANNING • Long-term plans for main transmission system • Reflection on criteria • Participation in NERC and NPCC PLANNING BY SUBSTATION • Asset sustainment plans
