Energy consumption in Thailand
On May 4, the first peak in energy consumption was measured this year, director Rerngchai Kongthong of the Energy Generating Authority of Thailand (EGAT) revealed.
The increase coincided with a higher average outside temperature (35,2 degrees Celsius), but remained just below the peak of last year 2016 with a value of 30.972 megawatts
The high electricity demand has been attributed to the higher temperature, as citizens use air conditioners and fans to lower the temperature. The lower peak can probably be attributed to an increase in energy-efficient equipment, which will be used more and more.
Although the consumption is attributed to the higher temperatures, the new large department stores (even with a “winter sports floor”) and hotels are also major consumers of energy.
Rerngchai notes that the EGAT will continue to closely monitor energy consumption as there have been major spikes in the past 3 years. If consumption rises to 32.059 megawatts, 3,5 percent higher than in 2016, additional generators in Bang Pakong and Ratchaburi will have to be turned on to meet demand. However, production costs and energy bills for the public will also increase.

My higher energy consumption is mainly due to the fact that the voltage collapses below 200 volts.
This means that larger currents will run in the cables – motors (of the air conditioner) consume much more current and power when the voltage is too low, in contrast to lamps – and more losses occur in the cables, causing the voltage to rise even further. decreases and the current increases.
Despite the considerable growth in the number of houses and air conditioners in the village, a transformer has never been added.
That is also the problem here, in my immediate vicinity there is a damage / repair company with welding equipment.
The moment you start welding, the voltage drops far below 200 volts, the moment the weld is 'released', the voltage rises to over 260 volts.
Complained several times, but you don't see anyone, and bigger transformers?? forget it.
And yes, I have backup/ups for the computer, but when overvoltage, the whole thing shuts down.
Extremely annoying, but what can you do about it.
Transformers consist of 220V in 220V. Varies the input voltage, the output voltage remains 220V. You can switch them between “sensitive” devices to protect them against overvoltage. If you want a transformer that can deliver high power then they are expensive, but for low power, computers for example, the price is not too bad. Most computers are equipped with an “isolation transformer” but they have a different purpose.
Forgot to mention:
there are very good "voltage stabilizers" with a decent capacity on the market. “EREA” is a manufacturer… have a look on the internet. Connecting is no problem.
Dear Ruud,
Your reasoning makes no sense. You are confusing recorded "Power in Watts" and "Power in Ampere". Yes, those two are dependent on each other, but there is a third factor and that is "Voltage in Volts". All this is directly proportional and the formula is:
P = U x I (Pouillet's law) In case, if the voltage goes down, the current goes up but the power consumed remains the same.
Your meter does not measure the current, but the absorbed power.
Example: a device with a power of 1000W, nominal voltage 22OV will draw approximately 4.5 A current. ( 1000: 22O= approx 4.5 )
the same device with a power of 1000W, nominal voltage 200V will draw 5 A current (1000: 200 = 5) but the power consumption, which is finally measured, is identical = 1000W.
Heavy voltage fluctuations are not healthy for some devices. If the voltage is too low, for example, a motor will draw too much current and can eventually burn, as the higher current will also cause a higher temperature and the insulating varnish layer of the windings will melt, but that will increase your consumption ???
In the case of incandescent lamps: they will simply give less light if the voltage is too low. If the voltage is too high, the filament in the lamp will burn out.
The fact that you get a “domino effect” when the voltage is too low and therefore higher current in the pipes is due to the fact that the power cables are too thin to pass that higher current and can therefore also heat up and possibly burn.
Dear Lung Addie:
My reasoning is spot on.
You're right about incandescent bulbs, but motors work differently.
When the motor is running, it generates a reverse voltage, which limits the current.
On a motor that does not run at all, for example because it is blocked, it has become a low-impedance resistor, which will soon emit clouds of smoke if it is not protected.
In that case, no work is done to cool the house, but only to heat up the compressor outside.
Therefore, the thermal protection is also activated.
The further the voltage drops below 220 volts, the more energy is used to heat up the compressor outside, because it does not run optimally at too low a voltage, and the less of the energy is used to cool the house.
The compressor therefore has to run longer to cool the house and will therefore use more energy.
The power cables of the house are of good quality and made of copper.
With a larger diameter than recommended (from memory 16 mm, but maybe that's not right) but they are long to the metre.
From the meter to the house I lose 5 volts when the air conditioner is running.
Good that you do a continuous measurement of the voltage, at least you can demonstrate that the energy supplier is failing. Or do you simply have the appliances and air conditioners on more often and/or for a longer period of time and therefore use more.
In the past, when I still had light bulbs, it was clearly visible that the voltage dropped.
About between 19.00 and 22.00.
It is sometimes also noticeable with the air conditioner, because the compressor will no longer start, because the compressor has become too hot and the thermal protection is blocking it.
This never happens during the day, when the temperature is highest, but probably at the beginning of the evening, when everyone turns on the rice cooker.
This clearly indicates that the problem is in the mains voltage.
However, I notice it most on my coffee maker (espresso) machine.
When the voltage has dropped to 200 volts, the water only comes out dripping and no longer forms a nice foam layer on the coffee.
And I think that's the worst.
No, I don't measure continuously, but I do occasionally plug in a voltmeter.
I have to look for a shop with staff who understand solar panels and backup power, who can also stabilize the 220 volts. (ex air conditioning)
I think the store will be there, but knowledgeable staff will be more difficult.
I saw voltage stabilizers at global house.
I don't think the staff can explain how to connect.
M.vr.gr.
Some stories don't quite make sense.
When the voltage drops, the current also drops, because the current is proportional to the voltage
If the voltage drops, the current also drops!!!
