TEN YEAR FORECAST OF FAULT LEVELS SEPTEMBER 2015
Introduction This publication presents an update to the ten year forecast fault levels report. The Connection Code contained in Schedule 8 to the Benchmark Agreement requires Transpower to publish a ten year forecast of the expected fault levels at each customer point of service annually.1 Transpower last published the Ten Year Forecast of Fault Levels in November 2014.
1 Connection Code clause 4.2(g): to publish annually a 10 year forecast of the expected minimum and maximum fault level at each customer point of service.

Ten year forecast fault Levels
Forecast fault levels calculation assumptions Calculated fault levels are very dependent on the assumptions used in, and method of, the calculation.
Minimum fault level calculations depend on generation and grid asset dispatch assumptions, and are generally used for ensuring the coordination of protection relays between asset owners. Protection coordination has very important consequences for power system security and safety of people and assets. Accordingly, we are not going to publish minimum fault levels which may be misunderstood and used in a way that threatens security and safety. We encourage connected parties to talk with us directly on matters concerning protection coordination.
Table 8 and Table 9 list the maximum three-phase fault current and maximum single-phase to ground fault current respectively for all Transpower’s transmission buses. Both tables list the 10 year forecast of fault current for existing grid configuration (BASE) and five generation scenarios (GS 1 to GS 5). The generation scenarios are based on the Ministry of Business, Innovation and Employment’s (MBIE’s) draft Electricity Demand and Generation Scenarios2 (EDGS) and work done by the New Zealand Smart Grid Forum3 on disruptive technologies. See Table 7 for generation scenarios description and the 2015 Transmission Planning Report4 for detailed explanation of each scenario. Table 1: Generation scenarios
Generation scenario Description
BASE Existing grid with committed projects at planned commissioning dates
GS 1 Scenario 1 – Mixed Renewables
GS 2 Scenario 2 – High geothermal access
GS 3 Scenario 3 – Low-cost fossil fuels
GS 4 Scenario 4 – Global low carbon
GS 5 Scenario 5 – Disruptive technologies
In Table 10 and Table 11, the listed value is the initial RMS symmetrical short-circuit current (𝐼𝐼𝑘𝑘′′) as defined by IEC 60909 2001.
The 10 year forecast of maximum fault levels is based on information currently known by Transpower. The values in the tables should be regarded as being indicative only. In BASE scenario, we have modelled committed future transmission upgrades and generation projects using the best information we have at this time. We know that towards the end of the 10 year period, there may be additional transmission upgrades and additional generation required to meet the power and energy requirements of New Zealand. We do not know exactly the nature or location of these future transmission upgrades and new generation. The maximum fault level at a transmission bus5 may also change where the number of supply transformers increase or get replaced as part of a Service Change to meet load growth or provide supply security.
Therefore the maximum short-circuit currents listed should not be relied upon for specifying short-circuit requirements for new substation equipment. The forecast fault levels provide an early warning of when plant capability may be exceeded. Accordingly, while Transpower

Ten year forecast fault Levels
endeavours to forecast fault levels accurately, the levels may change for a number of reasons and Transpower does not accept liability for other parties reliance on the fault values contained in the forecast. We encourage asset owners to consult with us for detailed information on maximum fault levels at specific sites relating to new equipment connection.
The Connection Code (5.1(h)) puts an obligation on Transpower and the customer to ensure its equipment does not cause the maximum short-circuit power and current limits in Appendix B Table B2 of the Connection Code to be exceeded on or nearby to the grid. Table 8 shows the short-circuit power and limits in Table B2 of Appendix B of the Connection Code. Note that the fault levels at some buses are already near or exceed these values. Table 2: Maximum short-circuit power and current limits

In BASE scenario, we calculated maximum fault levels in Table 10 and 11 using the 2001 IEC 60909 method. The values are the initial RMS symmetrical short-circuit levels.
The fault levels have been calculated on the following basis: • All generating units and all transmission assets are assumed to be in service. • A full representation of the existing transmission grid, directly connected generation and
embedded generation above 1 MW known to us is assumed. The existing wind farms are assumed to provide only full load current into a fault.
• Motor loads are not modelled. • The breaker time is 0.1 seconds and the fault clearing time is 1 second. • The fault impedance is zero ohms. • Future committed changes to the power system including transmission upgrades and new
generation detailed in the 2015 Transmission Planning Report. We represented new transmission lines in the model with electrical parameters estimated from the best matches with existing lines of the same conductor type. We have represented committed generation in our power system model with their electrical parameters scaled from the latest example which their type is known to us. We based the timing of these connections on open discussion with the asset owner, and from the generator’s website. The actual commissioning date may vary.
The generation scenarios GS1 to GS5 do not represent commitment from any generation developer and may change from year to year. The forecast maximum fault current in Table 10 and Table 11 are to provide indication on how the fault levels might change if the generation scenarios eventuate.
For scenarios GS1 to GS5, the maximum fault current calculation uses the same assumptions as per BASE scenario, and extended to include the following. • We represent the future generation in Scenario GS1 to GS5 with estimated from the best
matches latest technology with existing generator which their type is known to us. See Table 9 the assumption of fault current contributions from future generation in the generation scenarios.
• We assess each generator site and the grid injection point based on each generator’s operating capacity to ensure there is adequate transmission capacity to dispatch each generator.

• We do not include additional transmission upgrades (new transmission line, interconnecting
transformer or supply transformer) required to transfer the generation to load centres or provide supply security.
