Analysis And Research Of The Characteristics Of Power Plant Process Data

Papers in the process of thermal power plants took the data as the research object to study the data on the production process, several compression algorithms. First through the Huffman and LZW coding of thermal power plants to achieve a lossless data compression, and has achieved good compression. The use of well-known PI real-time database compression techniques, namely the exception reporting and spiral gate technology, the preparation of software implementation of the process lasted for data compression, and compression curves obtained dead zone, dead zone settings for the compression provides guidelines. PI database, the actual use of the time, how to set exceptions to the report provided the basis for dead zone. Respectively, wavelet compression and wavelet packet compression of the thermal power plants to achieve data compression process lasted all get better compression and faster processing speed.
