Here is just a brief introduction to what electric power people have to do. If you want to know more details, you can click on the power knowledge map website.
The three links of electricity are "power generation and transmission". Aside from the end link of electricity consumption, the top division of business between power generation companies and transmission companies is very close, and the core is five parts: engineering construction, equipment operation and maintenance, load dispatching, customer marketing and safety supervision:
Without equipment, there can be no power generation and transmission, so power equipment infrastructure is the initial business of power business. Engineering construction is the installation and construction business of power equipment, from building power plants and substations to expanding residential industry and laying cable trenches, which is equivalent to building houses in real estate.
According to the scale and source, power engineering construction can be divided into four categories: infrastructure engineering, technical transformation engineering, equipment overhaul engineering and user engineering.
According to the construction process, it can be divided into four links: planning, design, construction and acceptance.
You saw many construction projects in China, a big construction site. Half of the power projects are under construction, and the other half is the characteristic construction of power equipment, which will be carried out later.
When it comes to substantive business, we don't talk about "power generation" or "power transmission" because this is equipment doing work, while people are actually maintaining equipment. When the equipment is built and maintained, it can work for people and do a good job in power generation and transmission. Therefore, equipment operation and maintenance is the business with the longest power production time and the largest workload.
Power equipment operation and maintenance is the maintenance work of regular/irregular inspection, maintenance and replacement of equipment, which is the biggest job of power enterprises.
In the process of operation and maintenance and engineering, accepting the guidance and supervision of dispatching department and safety supervision department is also the greatest embodiment of power safety, so the comrades who do operation and maintenance are tired and mentally tired.
Power is an exquisite system. Low power systems need to control voltage and current, such as Five Blessingg Aon (5V 1A). Large power grid needs to control the load balance, fault shielding and safe operation of the whole power grid, and power generation needs to control the power quantity, frequency, internet access and energy type.
For large power grids and power plants, the customer marketing of electricity is close to monopoly in this link, and the price is close to transparency on the power trading platform. Customer marketing is basically business acceptance, service and settlement. Small and medium-sized power plants are relatively weak, and the price can be negotiated. In order to compete for online capacity, small power plants are still doing market work.
With the development of the electricity market, it could not be sold, and it was later demolished. The power plant has to talk with the power grid about the purchase quantity and price.
Power is an invisible killer, and power safety supervision is an important work of power. There are thousands of electric power safety laws and regulations, the core of which is operation safety, site safety and equipment safety. Personnel operation should have two-vote permission and other rules and regulations, and the job site should have safety facilities such as cleaning the site, power outage operation and high-tech operation. Equipment safety refers to the safety of operating equipment and people, such as safety helmet and grounding wire.
The implementation process of the monthly examination of power safety day school runs through engineering construction, equipment operation and maintenance, and power dispatching, which are all mentioned in the subsequent introduction of the above business.
Having finished the four dimensions of power enterprise, equipment, theory and business, we will introduce the commonly used power equipment in more detail.
