Coronavirus: On PM Modi's exhortation, India to light lamps at 9 pm today...

Switching off an electric lamp tonight is no harm to the "power grid"

When an electrical the network runs smoothly at its fixed voltage and frequency, sudden load drops or increases, it is normal for the entire network to be in charge. Although there are minor variations, it is restored before it reaches the client's courtyard.

Each country has its own power network, one national transmission center, one regional zone (five in our country) in each region, each state has a state transmission center and some provincial power stations under it. The responsibility of these dispatch centers is to ensure that the entire country's electricity network, within its scope and limits, operates continuously to provide power to the country's customers within its fixed frequency and voltage range. The efficient maintenance of the power network is a challenging task in a country with vast land areas and a large number of power consumers like India. The power network is a very dynamic system. Every now and then, millions of lights are lit and selected. Millions of pump sets are turned on or off. Office, Metro, Industry, Hospital, Airport... Everything is shut down when power is not needed. Thousands of the country's water, nuclear, thermal, diesel, solar, as well as biomass, gas turbines, etc., are generating power in their own capacity and for their own reasons (due to lack of water, lack of coal, economic problems, technical problems) Shut down.

It is also the largest network of power lines. Like the circulating blood vessels of the body, the hubby generates millions of kilometers in total voltage across the entire country, including AC power lines at 750 KV, 400KV, 220 KV, 110 KV, 66KV, 33 KV levels and DC power lines at 500 and 800 KV levels. Power is being transmitted from plants to substations. From there, the distribution lines are electrified to the streets at 11 KV and 400 volts to secondary streets to house houses.

But every day, as the constant circulation in our body, the country's electrical network is on, it must be running. (Examples of power outages have been interrupted between customers, in part because of shutdowns in their respective areas, but examples of power network collapses are rare recently). With the launch of the Raichur Solapur 750KV transmission line in 2013, the country's power grid is well secured. In addition, most state, zonal, and national power stations operate similarly to advanced countries, adopting technology such as the new 'SCADA' and DSM.

What would happen to the electrical network if the lamp was picked up at 9am tonight?

Before analyzing what will happen tonight, let's look at our country's electricity capacity. Our country's electricity capacity, including solar and wind power plants, is 3,68,960 MW. The total number of domestic consumers in our country is rural: 171364502, city: 43108539. That is a total of twenty-one crore forty-four hundred seventy-three thousand forty-one. The total lighting load used by all these customers is approximately 12,879 M Ws.

Last Sunday, March 29, the total demand for our national power network, (now due to the lock-down due to Corona) was 1,01,207 MW at six o'clock at 1,12,551 MW. At present, our country's lighting consumption is estimated to be ten percent (international level: thirteen percent. India average: eighteen percent. Blocking is great for a huge power network like India.

Similarly, if we look at the Karnataka power grid, our summit is currently around ten thousand MW, about ten percent of which is one thousand MW rising and collapsing (which is the highest estimate).

There are several ways to prevent voltage and frequency fluctuations:

If the load suddenly falls on the power grid, if some major transmission line is shut off if there is a sudden loss of load due to a large enterprise, or if the governor orders the shutdown of a city or town due to an accident, or load shedding due to a shortage of power, then the network freak. The voltage also goes up. Similarly, if a power plant like Sharavathi or Raichur suddenly stops, or if all the wind power plants start generating at the same time, the wind voltage and frequency will increase. In this case, the State Electricity Board, Zonal Transmission Station and National Electricity Board, which are in constant charge of power network operation, operate to keep the voltage and frequency at a fixed limit. They take steps such as shutting down the capacitor bank, operating the bus reactors, reducing the production of gas turbine and hydroelectric power plants. Relays such as DFBDT, which are adapted to the protection of electrical network safety, control the frequency and voltage increase, although they may be delayed for a while. Each power unit is equipped with a self-disconnecting DF/DT relay, which increases as the frequency increases. In addition, some power plants (especially hydroelectric units) have been placed in the Free Governor's Emergency to accept a sudden change of load. Posoko, a corporation under the Government of India, is responsible for managing all of India's power grid. India's sophisticated power network, which currently operates around one lakh twelve thousand megawatts of power, will take all precautionary and precautionary measures to reduce tens of thousands of megawatts of power, with just ten percent of lighting in homes across the country tomorrow night. It is understood that they have already sent the study report and notice to each zonal and state power outlet.

At eight and a half hours, a couple of routes were shut down, in terms of frequency and voltage management, as needed as a precautionary measure. Of course, it's not necessary. Even after the expiration, a couple of lanes slowed down. Not necessarily. But the electrical network is very sensitive. Someone else makes a slight difference somewhere else, or unfortunately, there is a sudden error in some other important way. But in my three and a half decades of experience in the power sector, no such phenomenon arises.

So what do we do today?

1. The Prime Ministers have said that choosing only electric lamps, we should come out wearing a mask, and light other kinds of lamps. So we must do as they say. In that case, devices such as a home fridge, fan computer, TV mobile charger should be running. Let’s put the fan out there, too. Let’s keep the grid running for the good of the good.

2. For those who have a borewell at home or a pump that pumps water from the tank to the lamp, let it run at the same time.

3. We are not alone in this situation where the Prime Minister of India is at home, as well as the rising corona, and the death toll of the country and abroad. Let us light the lamp with the goodwill of the citizens of the whole country, "Let the light of the world shine, and the light of all life."

4. It is not a homage festival to increase morale. So let the lighting of the lamp shouting, singing, clapping, beating and beating all over the world. What we are doing is for our own good. To the good of our nation. It is not a world to be exhibited.

5. Ours is a democracy. Someone may be reluctant to walk the talk of the Prime Minister and he may not light a lamp. There is no need to insult them, argue with them, quarrel. "To their devotion to their selves," we mumble in our goodness.

6. Do not turn on all lights at the end of nine minutes. First, just turn on blight and turn off the pump motors first. Then turn off the fans that are not needed. Then turn on the light one by one. Not everyone needs to go in and turn on the light for nine hours and nine minutes. Some wait for a slow, five to ten minute light. There should be no increase in load.

7. When the lamp shines, let us take care of our clothes and children. Today, let us wash the hands and light the lamp before God lights a lamp. Be very careful not to risk. Let the blasphemy work in silence and devotion.

It is for the welfare of humanity, beyond caste, creed, and religion...
