Reference excerpt

The Queensland – New South Wales Interconnector (QNI) is a 330 kV AC interconnection between New South Wales and Queensland, Australia. The link was commissioned in 2001. It consisted of double-circuit 330 kV lines between Armidale, Dumaresq Substation, Bulli Creek and Braemar and a double-circuit 275 kV line between Braemar and Tarong. There is an additional 330 kV Dual Circuit to complement the QNI from Bulli Ck Switching Station (27°55'15.8"S 150°50'34.8"E) via Millmerran Power Station & Switching Stations (27°57'53.7"S 151°16'26.9"E) to Middle Ridge Switching Station & 330/275/110 kV Sub, South of Toowoomba (27°37'22.2"S 151°56'43.0"E). The Dumaresq Switching Station (29° 12' 12"S 151° 19' 44"E) is in a rural area along Bruxner Way on the New South Wales side of the border with Queensland, and is located 21 km south-east of Bonshaw. The original maximum transfer capacity was 300 to 350 MW in both directions. This has been progressively increased to 700 MW from New South Wales to Queensland and 1,200 MW from Queensland to New South Wales. The interconnector is operated by TransGrid and Powerlink Queensland.

Worked examples

Example 1 — a first encounter with Queensland – New South Wales Interconnector

Start with the simplest possible case. Write down what Queensland – New South Wales Interconnector claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Queensland – New South Wales Interconnector before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Queensland – New South Wales Interconnector ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Queensland – New South Wales Interconnector

In research: Queensland – New South Wales Interconnector appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Queensland – New South Wales Interconnector in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Queensland – New South Wales Interconnector is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2001 establishments in Australia, Australian building and structure stubs, Electric power stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Queensland – New South Wales Interconnector outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
