HVDC Sileru–Barsoor

HVDC Sileru–Barsoor is a physics 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 Sileru–Barsoor rather than just read about it. In short: The HVDC Sileru–Barsoor is a high voltage direct current transmission system between Sileru and Barsoor in India. It is in service since 1989 as the first HVDC line in the country.

Key takeaways

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

Reference excerpt

The HVDC Sileru–Barsoor is a high voltage direct current transmission system between Sileru and Barsoor in India. It is in service since 1989 as the first HVDC line in the country. The HVDC Sileru–Barsoor is a bipolar HVDC with a voltage of 200 kV and a transmission capacity of 400 megawatts. The HVDC Sileru–Barsoor couples two asynchronously operated parts of Indian electricity mains over a 196 kilometres (122 mi) long overhead line, which was originally a double-circuit 220 kV AC line from which three conductors are paralleled. This HVDC line is not in use for a long time. On 1 January 2014, the NEW grid is synchronised with the Southern regional grid making this HVDC link redundant. 200 kV AC line of NEW grid can be directly connected to the 200 kV line of Southern grid bypassing the HVDC converter stations. Thus the energy losses taking place in the converter stations can be avoided and these HVDC converter stations can be shifted to elsewhere to export/import power from other countries. These unused converter stations owned by APTransCo, can be used to generate hydro electricity from Srisailam Dam or Nagarjuna Sagar Dam hydro power stations when the water level in the reservoirs are below the minimum rated water head by generating power at lower/under frequency (< 50 Hz). The lower frequency power is converted to normal grid frequency power with these converter stations. Thus more water available in the dead storage of these reservoirs can be used for additional power generation to meet peaking demand in summer months.

Worked examples

Example 1 — a first encounter with HVDC Sileru–Barsoor

Start with the simplest possible case. Write down what HVDC Sileru–Barsoor 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 HVDC Sileru–Barsoor 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 Sileru–Barsoor 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 Sileru–Barsoor

In research: HVDC Sileru–Barsoor 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 HVDC Sileru–Barsoor 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 Sileru–Barsoor is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1989 establishments in Andhra Pradesh, 2014 disestablishments in India, Electric power stubs, so understanding it makes those chapters shorter.
In everyday life: Look for HVDC Sileru–Barsoor 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.
