Description
Technical Field
The invention relates to the technical field of wind power generation, in particular to a master control system of a wind generating set.
Background
Wind energy is the kinetic energy generated by the bulk air flow at the surface of the earth. Because the temperature change is different and the content of vapor in the air is different after the ground is irradiated by the sun, the difference of the air pressure in each place is caused, and the high-pressure air flows to the low-pressure area in the horizontal direction, namely, wind is formed.
Wind energy resources are determined by wind energy density and the cumulative hours of available wind energy per year.
The world meteorological organization estimates that the global wind energy is about 2.74 x 109MW, wherein the available wind energy is 2 x 107MW, which is 10 times greater than the total amount of water energy which can be developed and utilized on the earth, and is equivalent to the energy generated by 10800 hundred million tons of standard coal, which is about 100 times of the current energy consumption in the world.
Wind energy density is the power of the wind available per unit windward area, and is proportional to the third power of the wind speed and the air density. Wind energy resources are greatly influenced by terrain, and are mostly concentrated in coastal and open continent contraction zones, such as the coast of California in the United states and countries in northern Europe, and the coastal, inner Mongolia, Xinjiang and Gansu areas in the southeast of China are also rich.
Wind power generation refers to a power generation mode of directly converting wind energy into electric energy by using a wind generating set. Among various utilization forms of wind energy, wind power generation is the main form of wind energy utilization and is one of the most mature technologies, the most large-scale development conditions and the most commercial development prospects in renewable energy sources at present.
Currently, wind energy has been developed to account for only a small and insignificant portion of the world's wind energy resources. If 50% of the wind energy resources are utilized, the world power demand can be met. In our country, wind resources are listed third in the world, ranked after russia and the united states. According to the latest wind energy resource assessment, 3 hundred million kilowatts of wind energy resources can be utilized on land nationwide, and the total amount of the wind energy resources can be about 10 hundred million kilowatts in offshore areas.
The wind driven generator is a comprehensive technology integrating aerodynamic force, motor manufacturing, hydraulic transmission and computer automatic control. The system is composed of the following subsystems: the system comprises blades, a speed-increasing gear box, a generator, tower control equipment, cables, ground support equipment and subsystem connecting equipment.
Wind turbines are the most important parts of wind power systems. The proportion of the unit to the initial investment of the wind farm is very large, generally 60-70%. This is why the country stresses to make wind turbines localized as soon as possible.
The electronic technology, automation and computer technology widely used in the aspects of control systems and protection systems not only can effectively improve and improve the overall design capability and level of wind power generation, but also has an important role in enhancing the protection function and the control function of wind power equipment.
The electric control system of the wind farm is an important part of the core technology and is collectively called the heart of the wind turbine. The research of the whole wind power plant control system comprises an automatic control system based on a wind turbine generator, a wind power plant central monitoring system and a whole wind power plant equipment information operation and maintenance management system.
The cabin control station in the electric control system of the wind power plant plays a role in brain control center, and generally, a power distribution cabinet has a large number of wires, wiring is complicated, time-consuming and unattractive, so that the cabin control station convenient for wiring needs to be designed.
