The renewable energy such as solar energy, wind power, tidal energy and geothermal energy comes from nature, which is endless and inexhaustible and of little harm or even harmless to the environment. What’s more, these resources are widely distributed. If they are exploited and utilized properly, it’ll be of great significance to environmental protection and resources protection.

The system has following advantages:
high integration level: except wind turbine generators, photovoltaic equipments and water tanks, other equipments are all put inside the container. With compact layout and good flexibility, it is convenient for transportation;

clean energy: only use clean energy for energy saving and environmental protection; and there is no pollution to marine environment;

black start function: the system can start operation without any support of power;

highly automatic: during operation, the system can start with a push of button; and the operation is automatic with remote monitoring function;

protection design: the system is featured with typhoon defense, corrosion protection and high temperature resistance functions;

The system adjusts to a big range of water quality fluctuation; the pretreatment system does not need chemical cleaning. Reverse osmosis system does not require frequent cleaning. It releases very limited chemicals to the environment, and therefore is pollution-free. The routine operation cost for the system is very low. The maintenance of the system is simple and convenient, which is not labor intensive.

Not only can the integrated system of modular intelligent microgrid and seawater desalination can supply living water and electricity to our remote islands and inland brackish water basins, but also the seawater desalination technology is an important part of China marine strategic emerging industry. The technology can be widely applied to vessels to avoid water shortage during long-distance travel. In the meanwhile, the complete container modular intelligent microgrid desalination system may not only be integrated, but also be disassembled into the microgrid system and the desalination system to be respectively used in the areas lacking in electricity but not lacking in water and the areas lacking in water but not lacking in electricity.

Microgrid system
The microgrid system operation mode includes normal operation mode (operation mode combining wind energy with energy storage), complementary operation mode of wind energy and diesel generated energy, complementary operation mode of wind energy, diesel generated energy and energy storage, the operation mode by introducing external power.

When the wind power is strong enough to start the wind turbine generator, the wind turbine generator works normally and the system is in the wind power storage operation mode. Otherwise if the generated wind power cannot meet the operation conditions of seawater desalination equipment, the system needs extra energy supply from the outside to guarantee its operation. The system has a various operation modes like complementary operation mode of wind energy and diesel generated energy, complementary operation mode of wind energy, diesel generated energy and energy storage, the operation mode of independent diesel generator power supply, the operation mode by introducing external power. These modes can be inter-converted. The normal operation mode of the microgrid system combines wind energy with energy storage. In such mode, it’s unnecessary to start diesel generator and the diesel generator is only used in special cases or for the purpose of guaranteeing the diesel generator’s safe shutdown.

Generally there’re 30kw, 50kw and 100kw wind turbine generator for selection. At present, 100kw is mostly chosen based on the analysis of performance and application maturity. The 100kw wind turbine generator applies automatic pitch control structure, and the rest replies on manual control. Therefore, 100kw wind turbine generator is slightly safer.

The capacity of seawater desalination system can be customized as per customer’s demands. There’re mainly 50T, 100T, 200T, 300T, 500T, 1,000T specification for customer’s choice.
