In recent twenty years, vicious accidents mainly caused by vibration have occurred one after another, which has caused huge economic losses to the country. Moreover, the vibration problem is still the main reason why the new large units can not be connected to the grid on schedule and put into operation normally. In the process of normal operation of the unit, vibration problems continue, affecting normal production, often leading to load reduction, sick operation of the unit, and even forcing the unit to stop processing. These accidents are very common. Based on LabVIEW virtual instrument software platform, the system reads and windows the vibration signal of steam turbine, and carries out spectrum analysis and autocorrelation analysis. LabVIEW virtual instrument is a computer instrument system which is designed and defined by users, has a virtual front panel, and realizes the test function through test software on a hardware platform with a general computer as the core. The system mainly completes the reading of steam turbine vibration signal, the window selection of rectangular window, Hanning window and Hamming window, and then carries out amplitude spectrum, power spectrum, phase spectrum analysis and autocorrelation analysis on the signal respectively, and has graphic operation and display interface. The running results of the system prove that the system can read signals, dynamically select three kinds of window functions and various analyses, and display the results in a graphical way.

In recent 20 years, fatal accidents mainly caused by vibration have occurred one after another, causing huge economic losses. In addition, vibration is still a new power grid for large units, the main crew members in normal operation are working normally, continuous vibration problems affect normal production, units often reduce load and get sick during operation, and even units are forced to stand. These incidents are not uncommon. Based on LabVIEW virtual instrument software platform, the system reads the vibration signal of steam turbine in the window, and carries out frequency spectrum analysis and correlation analysis. LabVIEW virtual instrument is a universal computer hardware core platform, which is defined by users and has a virtual front panel. The test function comes from the test software of computer equipment system. The system completes the reading of steam turbine vibration signal, the selection of signal rectangular window Hanning window and Hamming window, and then the amplitude spectrum, power spectrum and phase spectrum of the signal are analyzed and correlated, and the operation is carried out by graphics and display interface. The running results of the system show that the system can complete signal reading, three-window function, dynamic analysis of various options and graphical display of results.

Motor vehicles are not the only air polluters. Coal and oil used for heating in homes and factories and generating electricity contain a small amount of sulfur. When fuel is burned, it will produce toxic gas sulfur dioxide. Irritating to the lungs. Some cities have passed laws that only allow coal and oil to burn with low sulfur content.

Cars are not the only air pollution. Coal and oil used for home heating and factories can generate electricity and contain a small amount of sulfur. When fuel is burned, it will produce toxic gas sulfur dioxide. Irritating to the lungs. Some cities have passed laws that only allow coal and oil to have low sulfur content when burned.

Most electricity is generated by steam turbines. About half of the sulfur dioxide in the air comes from burning fuel to make steam. Nuclear power plants do not burn fuel, so there is no ordinary air pollution. However, radioactive materials in these nuclear power plants may bring danger in accidents. In addition, it is also a problem to treat radioactive waste in a way that does not harm the environment.

In addition, there is a problem that radioactive waste will be treated in a way that will not harm the environment.

Another type of pollution, called thermal pollution, is caused by fuel combustion and nuclear power plants. Both need a lot of cold water, which cools the steam and warms it at the same time. When it returns to the river, warm water may stimulate the growth of weeds. It may also kill fish and their eggs, or interfere with their growth.

Physicists are studying new ways to generate electricity, which may cause less damage to the environment. At the same time, many power plants are undergoing modernization to reduce the emission of pollutants. In addition, engineers try to design and locate new power plants to minimize the damage to the environment.
