Generator detection method and device thereof

The present invention relates to a generator detecting device, and more particularly to a device that can test various data of a generator to detect its power generation efficiency.

In view of the oil crisis in the late 1970s, many European and American countries began to seek energy outlets. In terms of Taiwan's power generation industry structure, in 1999, 67% of electricity came from thermal power generation, 27% of electricity came from nuclear power, and 6% of electricity came from hydropower. Many advanced countries question the economic benefits of nuclear power generation. In the case of Britain, the United States and Germany, after the liberalization of the electricity industry, many nuclear power plants are automatically shut down due to low economic efficiency, and nuclear power generation is not only economically but also in nuclear energy. Nuclear waste and nuclear power plant accidents generated during power generation are more likely to bring endless disasters to future generations. As for thermal power generation, oil is dependent on imports, and there are related effects of national security and economic autonomy, and the environmental pollution caused by it cannot be ignored. In addition, hydropower generation currently accounts for only a single digit in China, but the damage to the natural environment and river turbulence should also be carefully evaluated.

Therefore, the wind power generation equipment mainly includes a windmill and a generator. Two major parts.

Change) and other power generation equipment problems, so often waste too much manpower and cost in the detection of power generation efficiency.

Therefore, how to solve the problem of power generation efficiency detection of the above-mentioned conventional generators is the focus of the creative solution.
