Electric power stabilizing device suitable for offshore floating power station and application thereof

Abstract

The invention relates to the field of heat and power, and in particular, relates to an electric power stabilizing device suitable for an offshore floating power station and an application thereof. Alternating current passes through an electrode arranged in water through a negative charge balancing device, water is used as an electric-conducting medium, and water resistance is changed to serve as a load; electric energy generated by a floating power station electric generator set is absorbed to achieve loading of the system, a large amount of electric energy is consumed, loads can be rapidly changed under the control of a data collection and microcomputer monitoring management system, and when the power capacity of a heating element of the system is equal to the capacity of load impact in a power grid, real-time load tracking can be achieved; the device is used for stabilizing load impact in the power grid, improving power supply reliability and solving the safety and stability problems of a remote sea island isolated network operation power station.

Description

technical field [0001] The invention relates to the field of heat and power, and more specifically relates to an electric power stabilization device and application suitable for offshore floating power stations. Background technique [0002] There are many islands in our country, and for most of the islands, the biggest problem at present is the long-term lack of water and electricity, which seriously restricts the rapid development of residents' life, resource development, industrial production and local economy in remote seas and remote islands. [0003] At present, there are two main modes of island power supply, one is networked and the other is isolated network. For medium and large archipelagos that are closer to the mainland, because of the large demand, networked power supply is often used, using submarine cables, and if the distance is not far, overhead large spans will also be used to transport power. This power supply mode has large power supply and high reliabil...

AI Technical Summary

Problems solved by technology

This power supply mode has large power supply and high reliability, but the construction cost is high and maintenance is difficult. For many remote islands, the isolated grid power supply method is adopted. At present, diesel generators, wind energy, solar energy and other methods are mainly used.

[0004] Offshore floating power station is a special engineering ship that builds power plants on barges to provide power services. It has the advantages of maneuverability, convenience, short construction period, less pollution, and does not occupy land. The number of generator sets in a type power station is small, and the kinetic energy stored by its rotational inertia and the thermal potential energy of the boiler group are both small. Therefore, when some facilities with large impact loads such as smelters are in use, the impact of their electrical loads has a great impact on isolated The frequency and voltage impact of the network are large, which will seriously affect the safety of the isolated network and the life of the main equipment, resulting in low system reliability
