Industry Background:

With the accelerating process of global warming, the concept of caring for the earth, environmental protection and energy saving has become more and more popular. As a kind of renewable and clean energy, wind energy is becoming a new energy vigorously promoted by all countries in the world under the situation of energy shortage and serious pollution in the world today. The two main components in a wind power system are wind turbines and generators. Wind turbines are developing towards variable pitch adjustment technology, and generators are developing towards variable speed constant frequency power generation technology. This is the development trend of wind power generation technology, and it is also the core technology of wind power generation today. The pitch adjustment method is to change the angle between the windward surface of the blade and the longitudinal axis of rotation, thereby affecting the force and resistance of the blade, limiting the increase of the output power of the fan in strong wind, and maintaining the output power constant. Variable-speed constant-frequency wind turbines often use AC excitation doubly-fed generators, which are similar in structure to wound induction motors, except that slip rings and brushes are added to the rotor windings. Thus, the rotor speed is related to the excitation frequency. , so that the internal electromagnetic relationship of the doubly-fed generator is different from that of the asynchronous generator and the synchronous generator. However, variable-speed constant-frequency wind turbines have certain characteristics of asynchronous machines and synchronous machines, both of which require stable operation of the system in harsh environments.

Application Requirement:

In order to ensure continuous and safe power supply, wind turbines must continuously and reliably generate electricity through wind energy conversion under extreme conditions, and can be controlled and monitored in a timely and effective manner. The power plant information management system is designed to collect raw data from hundreds of wind turbines and turn it into intelligent data information. At the same time, the processed intelligent data information must be able to be stored for a long time in order to analyze the historical records and further improve the power generation efficiency.
