Study and Application of Integrated Power Network Planning Information System

Abstract

An integrated power network planning information system is developed, which can not only serve the business management functions of power network planning, but also provide assistant decision-making functions for planning. The system consists of three components, i.e. the basic data platform (BDP), planning business management subsystem (PBMS) and planning decision-making support subsystem (PDSS). BDP manages various kinds of basic data for planning, including socio-economic data, power plant data, power network equipment data, electricity demand data, load data, and so on. Meanwhile, BDP provides data supports for PBMS and PDSS. PBMS manages the working processes of various planning businesses, which come from the planning department of Guangdong Power Grid Corporation (GPGC), and are abstracted as workflows in the system. PDSS offers some computer-aided analysis and decision-making functions for planners in planning and project management processes. Applications and implementations in practical planning workshow that the proposed system can improve the informatization level, management and efficiency of planning work, versus traditional work patterns.

Load Forecasting of Coal-Fired Unit Based on SVM Model

“…With the aid of CCD cameras arranged at different heights of boiler, multilayer flame images that reflect combustion intensities of various areas were taken. In recent years, using the flame images to detect radiation signal, and analyzing the relationship between flame images and unit load, have made some progress [1][2][3].…”

“…Base on the two-color method, reference [1] detects radiant energy signal, and fits the linear static relationship between it and unit load. According to the detection of radiant energy signal, the unit load can be predicted.…”
