HVDC Gezhouba–Shanghai

HVDC Gezhouba–Shanghai is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand HVDC Gezhouba–Shanghai rather than just read about it. In short: The HVDC Gezhouba–Shanghai is a high voltage direct current electric power transmission system between Gezhouba and Nanqiao near Shanghai, China put in service in 1989. The bipolar 1,046-kilometre (650 mi) line is rated at 500 kV and a maximum power of 1,200 MW.

Key takeaways

HVDC Gezhouba–Shanghai belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect HVDC Gezhouba–Shanghai to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HVDC Gezhouba–Shanghai from memory before moving on to harder problems.

Reference excerpt

The HVDC Gezhouba–Shanghai is a high voltage direct current electric power transmission system between Gezhouba and Nanqiao near Shanghai, China put in service in 1989. The bipolar 1,046-kilometre (650 mi) line is rated at 500 kV and a maximum power of 1,200 MW. Between 2008 and 2011 the towers of the most part of the line, which were almost guyed towers capable of carrying two conductors, were replaced by new free-standing line towers for 4 conductors in order to install the conductors for the HVDC Hubei-Shanghai on them. This 970 km long line, which is also a bipolar HVDC with an operating voltage of 500 kV runs from Jingmen to Fenjing and has a transmission capacity of 3000 MW. HVDC Hubei-Shanghai shares also the grounding electrode of HVDC Gezhouba–Shanghai for the Nanqiao terminal. For most of its length, the electrode line of HVDC Gezhouba–Shanghai carries also the electrode line of HVDC Hubei-Shanghai. HVDC Gezhouba–Shanghai carries between Fenjing and Nanqiao also the electrode line of HVDC Hubei-Shanghai in most part of its length on its towers. The grounding electrode of HVDC Hubei-Shanghai at Chujiahu is also used by HVDC Three Gorges-Changzhou.

Worked examples

Example 1 — a first encounter with HVDC Gezhouba–Shanghai

Start with the simplest possible case. Write down what HVDC Gezhouba–Shanghai claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 HVDC Gezhouba–Shanghai 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 HVDC Gezhouba–Shanghai 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 HVDC Gezhouba–Shanghai

In research: HVDC Gezhouba–Shanghai appears in engineering 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 HVDC Gezhouba–Shanghai 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: HVDC Gezhouba–Shanghai is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1989 establishments in China, Chinese building and structure stubs, Electric power infrastructure in China, so understanding it makes those chapters shorter.
In everyday life: Look for HVDC Gezhouba–Shanghai 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.
