What Is Power Industry Analysis?

Power analysis refers to the study of the characteristics of the power production and consumption system consisting of power generation, transmission, transformation, distribution, and power consumption.

Power analysis refers to the study of the characteristics of the power production and consumption system consisting of power generation, transmission, transformation, distribution, and power consumption.

The main content includes basic knowledge of power system, equivalent circuit and power flow calculation of power system, active power balance and frequency adjustment of power system, reactive power balance and voltage adjustment of power system, calculation and reduction measures of power loss, Stability analysis, long-distance transmission, grid structure and typical accident analysis, mechanical calculation of overhead lines, power network design, etc. ^[1]

1. Power flow calculation, a basic electrical calculation that studies the steady-state operation of the power system. The task of conventional power flow calculation is to determine the operating status of the entire system based on the given operating conditions and network structure, such as the voltage (amplitude of each bus) Value and phase angle), power distribution in the network, and power loss. The result of power flow calculation is the basis of power system stability calculation and fault analysis ^[1]

In recent years, China's rapid economic development, especially the prominent industrial development, has promoted the demand for electricity. However, there are regional differences in the growth of electricity consumption, and the growth of electricity consumption has regional imbalances. Electricity is growing at a fast rate, while the economic growth rate in the central and western regions is relatively slow. The electricity consumption in China shows a structural difference, and this difference gradually expands with the continuous development of the economy.
