What Is Power Transmission and Transformation, And What Is the Principle?
The power system includes "transmission, transformation and distribution" electricity, commonly known as transmission and distribution, transformation and distribution, etc. Number one, substation. Such as a certain 35kV substation. The effect of the substation boosts and bucks. It can be understood as a water pumping station, and you can also look at the operation process of the ships passing through the Three Gorges Reservoir, which is somewhat similar. The remote meter reading system is introduced to you as below.
Substation all primary, secondary, terminals.
Power. The power that drives the generator to rotate. Some enterprises generate coal-fired power for their own use, and some of them are sold to the grid. Some are hydro, like some reservoirs. Some are nuclear, and there is an officially operating nuclear power plant nearby. Another one, which started many years ago.
Electricity generation. Some businesses have generators. Some use electric operating mechanisms to automatically operate diesel generator sets to start and stop in the event of a power outage or power call. Some are temporarily mobile diesel generators.
Before operating the diesel generator set, the operator should carefully read the operating instructions of the generator set, diesel engine, motor and control panel that are equipped with the generator set. Please be careful when adding oil and cooling water. Read the nameplate of the generator set carefully, and the generator should cut off the load first and then stop.
Dual power supply. Regarding the process of dual-circuit power supply, strictly implement the technical and organizational measures of safety regulations. The process of power outage and transmission is described in the previous chapters, multiple people cooperate to operate, organize special personnel to guard, etc. Once the generator was operated, it was fixed with wire because it was covered with a tarp. When dismantling the tarpaulin, the wire was thrown at random and onto the battery of the generator, causing an instant short circuit. Thankfully my partner found out in time. Operation at night requires more caution.
If you haven't touched the principle of the generator, you can find the relevant video animation to see it. It doesn't work well in words. Under the summary of the remote meter reading system, power plants generate electricity, substation boost, high voltage transmission, substation step down, and low voltage distribution. In the end, the power transmission part uses cables and extends to two points. Under the condition of constant power, the voltage is high, and the current is small. P=U*I (power factor). One factor in choosing the cross-sectional area of the wire is to consider the magnitude of the current. R=ρ*L/S UHV DC transmission, rectification, and inverter, you can study it if you are interested.
