Assessment On City Power Grid Capacity Of Baotou

Baotou City is the country's important industrial base and transportation hub, the center is the largest city in Inner Mongolia. To grasp the power supply capacity of Baotou City Network (potential), economic operators to improve the level of urban network security for urban network "second Five-Year " plan implementation of the project to provide accurate basic data, it is necessary to assess in Baotou city grid.Power supply capacity assessment is the core of the assessment. In this paper, urban power supply capacity assessment conducted in-depth research, combined with the characteristics of Baotou city power grid power supply capacity is proposed indicators will be introduced to the largest evaluation of the ability to supply and evaluation of city power grid as the key level of competence Indicators.Based on current trends and the model of linear programming theory, a maximum supply capacity of the network indicators for solving the linear model; this model, the network can supply the maximum load as the objective function to the network power balance, line and transformer Transmission power and power transmission capacity constraints, power generation, power side and consumption side of the basic constraints constraint, fully considered the impact of urban power supply capacity in all aspects. The paper gives a mathematical description of linear and standardized format, gives the calculation, the solution process, using the model city of Baotou supply capacity of the grid to assess the supply of Baotou city grid margin, N-1 checking line, short circuit, power flow, etc., the final grid for the current problems in the city of Baotou and optimization recommendations.The results of this study for the urban grid planning, assessment provides a useful exploration.
