In recent years, renewable energy distributed generation technology is introduced into power system through micro grid. As a rapid developing direction in the field of smart grid, short-term load forecasting grid very important work. More accurate can strengthen management However, due to non-smoothness and non-linearity load, microgrid complicated task. Taking university office building as an example, this paper expounds difference between traditional time series, proposes prediction...

In electrical exploration techniques, an effective suppression method for Gaussian and impulsive random noise in spread-spectrum induced-polarization (SSIP) data continues to be challenging conventional denoising methods. Remnant influences the complex resistivity spectrum damages subsequent interpretation of geophysical surveys. We have developed a hybrid based on correlation function resistivity, which introduces analyses among transmitting source, measured potential, injected current...

Abstract The data format of the current substation 3D design results is inconsistent, and different software platforms not connected. For problem these, this paper analyzes status mainstream comprehensively, establishes a standard database framework that suitable for engineering, which can ahieve cross-platform integration utilization, provide technical support formation State Grid Corporation’s standardization model library.

Abstract This paper compares the temperature and dust concentration distribution of blast furnace cast house under different removal design conditions external climate by means on-site sampling, field measurement data analysis. It is found that post in closed 2.4°C lower than open design, but 0.139 mg/m 3 , which 1/10 design. Therefore, recommended. Different climatic also have influence. suggested to close main wind direction doors windows when outside speed high avoid turbulence.

In order to solve the problem of energy consumption, improve efficiency utilization and develop new energy, total consumption fluctuation thermal integrated were analyzed. Four suggestions are put forward for power system flexible plant, namely, electric heat storage system, pump g, heating high pressure via steam turbine, which can air capacity reduce coal system. Among them, in case small conditioning units or do not use furnace furnace. Heat technology unit is suitable daily exhaust....
