Definition of words
[Words]: Grid connection
[Phonics]: b ì ng w ǎ ng
[Definition]: the transmission line of the generator set is connected to the transmission network (starting to transmit electricity outward). For example, the grid connected generation of new units alleviates the shortage of power supply.
<English>
<Japanese>Connect to the appropriate power supply
Grid connected power generation means that it is connected to the power supply grid for operation when generating power. Because power supply and power generation are separated in most regions, the power station needs to obey the power supply dispatching, so that you can generate power only when you send it to the grid. Otherwise, you can only send your electricity to the line of your power station and substation if you generate electricity from the substation disconnect switch. It's useless to generate electricity without being consumed by residents and factories. Dispatchers will let you generate electricity depending on the demand of your local power grid. If there is a power shortage, they will let you generate electricity. If there is a large power station with continuous power generation and reliable voltage, they will use large power stations.
[Benefits of grid connected power generation]:
All power plants have the problem of grid connected power generation. If they are not grid connected, that is, off grid, they will have low power generation efficiency and lower power generation quality. For example, if their own power generation uses less, they will have to generate less power. If they use more, they will not generate enough power, Power quality instable. After grid connection, there is no such problem. More power can be sent to other users on the grid, while less power can be used to supplement, and the power quality is relatively stable. [Requirements for grid connected power generation]
1. The voltage is the same, 220 V in mainland China, 110 V in Taiwan, 230 V in Europe and 120 V in North America;
2. The frequency is stable, 50 Hz in the mainland, 60 Hz in Taiwan, 50 Hz in Europe, and 60 Hz in North America;
3. The phase is the same, which requires accurate timing matching. If there is deviation, current will be generated on the zero line, wasting power.
