基于PowerWorld的电网潮流计算

Power Flow Calculation of Power Grid Based on Power World

随着国民经济快速发展,工业及社会的用电量逐年增加,整个电力网络也随着用电量的增加而不断扩大。面对电能需求的增加,为保证供电可靠性和经济性,要考虑到电源计划,同时必须从电力系统的全局来考虑全系统构成和控制。而且,在运行中还必须针对时时刻刻变化的负荷,最大限度地发挥各种设备的能力,使整个系统稳定、优质、经济地运行。本文应用Power World仿真软件对广西南宁市区电网进行建模分析,直观地计算出其线路负载状况和电压水平,以评价运行方式的合理性,对电网的规划和发展提供合理的建议。

With the development of the national economy, the power consumption of industry and society increases year by year, and the power grid also expands with the increase of electricity consumption. In order to ensure the reliability and economy of power supply, the power supply plan must be taken into account in the face of increasing demand. Mean- while, the whole system configuration and control must be considered from the overall power system. Moreover, in the op- eration must also be aimed at users always changing, to maximize the ability of a variety of equipment, so that the whole system stable, high-quality, economical operation. In this paper, PowerWorld simulation software is used to analyze and analyze the Nanning urban power network. The load status and voltage level of the line are calculated visually to evaluate the rationality of the operation mode and provide reasonable suggestions for the planning and development of the power grid.
