Renewable energy storage systems to power the future

The most efficient way to store – and deliver – energy coming from renewable sources is through battery-based renewable energy storage systems. The more battery storage for renewable energy that is available the less there will be a need for the conventional power sources of the past.

25 kV AC railway electrification in Hong Kong

Hong Kong MTR uses electric trains, powered by two different technologies – 1500 V DC on the ''urban'' rail lines, and 25 kV AC for the former KCR network. Today we look at 25 kV AC railway electrification across Hong Kong. Which have transformers to convert 132 kV power from the CLP Group grid to the 25 kV power used by the railway system.

Transformer and Reactor Storage

Ever since the first power transformers were introduced in the 1880s, delays in transportation and installation have resulted in a need to put transformers into short-term storage. The growing importance of a reliable electricity supply to the economy and modern society led to a need for spare transformers and reactors, which sometimes needed

6 FAQs about [Hong Kong power transformer storage]

Why are harmonic Transformers a problem in Hong Kong?

Most of the distribution transformers in Hong Kong are provided by the two power supply companies and all these transformer losses are therefore absorbed by the power companies. Harmonics produce extra losses in transformers and these costs could not be recovered from their consumers.

What is a typical supply voltage waveform in Hong Kong?

A typical supply voltage waveform at a consumer’s metering point (or point of common coupling) normally doesn’t exceed 5% THD in Hong Kong but for some high-rise commercial buildings, the voltage THD exceeding 10% is not uncommon especially at those higher level floors fed with a common rising mains.

Which equipment will be accommodated in separate rooms for underground transformers?

The CLPP 11kV equipment receiving power from different sources will be accommodated in separate rooms for underground transformers . The check metering system comprises the digital energy meters, metering server and communication equipment. Digital energy meters as check meters will be provided at each CLPP metering point.

Can a distribution transformer supply a non-sinusoidal load current?

IEEE paper C57.110, entitled “IEEE Recommended Practice Establishing Transformer Capacity When Supplying Non-sinusoidal Load Currents”, details two methods for de rating distribution transformers as a result of the additional heating effect that occurs when these transformers supply power loads that generate a specific level of harmonics.

Can power factor correction capacitors be installed in Hong Kong?

Supply companies in Hong Kong do not permit their customers to have the power factor fall below 0.85 at any time. Power factor correction capacitors can be installed anywhere in the power distribution system.

How many kV transformers will be provided at WKT?

The typical CLPP 11/0.38kV transformer capacity of 1,500kVA and 2,000kVA transformers will be provided to suit the load demand. In addition, dedicated transformers will be provided at WKT for non-railway operating loads, including loads for Custom, Immigration and Quarantine (CIQ) facilities and Station Trading Area (STA).
