Power grid industry

      With the promotion of the national "carbon peak and carbon neutralization" policy and related work, the two power grid companies in China put forward the control strategy of taking access to clean energy as the main body on the power side, strengthening the consumption, energy storage, stability and safety of the power grid, and adopting the scheme of electric energy substitution on the user side. Under this development background, China's energy structure will be fastly developed from fossil energy to clean and low-carbon energy. Renewable energy power generation will enter a large-scale "double speed" development stage, and the proportion of non-fossil energy such as wind power, photovoltaic, hydropower and nuclear power will increase significantly. Accelerating the construction of new power system will have a profound and great impact on the development of power industry in the next 40 years. To achieve the "double carbon" goal, the energy field is the main battlefield, the power industry is the vanguard, the equipment manufacturing industry is the core support, and the power transmission and transformation equipment is the core priority. Facing the national "double carbon" goal and the action plan of major power users, Baiyun Power Group is supporting the construction and development of new power system by direct emission reduction, energy conservation and consumption reduction, supporting carbon reduction and green technology, and launch the following solutions: flexible DC transmission system solution, intelligent substation solution, prefabricated cabin substation solution and intelligent distribution grid solution.

port

After berthing, the ship is usually powered by the diesel generator on board. The emissions of nitrogen oxides, sulfur oxides, CO2 and particulate matter generated after the combustion of marine fuel will pollute the port and the surrounding environment.

Shore power supply system refers to the power transmission system that seamlessly transfers the power load on board to the shore by connecting the shore power supply of the wharf and turning off the ship side generator when the ship is docked. In order to meet the requirements of 60Hz power supply system for international ships, a special frequency conversion shore power supply system is required to convert the 50Hz power supply of shore power grid to 60Hz.


The application of shore power supply system can greatly reduce the pollution emission when the ship is berthing, reduce the emission ratio of nitrogen oxide, particulate matter and sulfur oxide by about 90%, eliminate the noise and vibration generated by the generator on board, improve the operation and living environment of the crew, and reduce the unit loss and maintenance.
