发布时间：2018-12-15 14:51
【摘要】：随着国家经济的快速发展和人民生活水平的提高,人们用电需求日益增长,同时对供电质量和供电可靠性提出了更高的要求。由于负荷的不断增加,以及电源的大幅增加,对电网要求也要改变。 为开发某一中等城市，现要构建一个具有10至15年远景规划的电力网，全面负责本城市的供电。结合该市的远景规划设想和地理位置，根据该城市的负荷情况，设计220kV和110kV的电力网。为了使电网能够稳定可靠经济的运行，本设计对该城市的电力电量平衡，无功功率的验算，看它是否符合要求，进行优化。在考虑远景负荷下，选择合适的变压器、导体和母线。应用PSASP软件对该电网短路计算、潮流的计算，，检验电网是否符合要求。最后介绍新的可靠性指标对电网的可靠性检验。
[Abstract]:With the rapid development of national economy and the improvement of people's living standard, people's demand for electricity is increasing day by day. At the same time, higher demands are put forward on the quality and reliability of power supply. Because of the increasing load and the large increase of the power supply, the requirements of the power grid will also change. To develop a medium-sized city, a power grid with a 10-to 15-year vision is now being constructed, with overall responsibility for the city's power supply. Combined with the vision and geographical location of the city, the power network of 220kV and 110kV is designed according to the load situation of the city. In order to make the power grid run stably and economically, this design checks the balance of electricity quantity and reactive power in the city to see if it meets the requirements and optimizes it. Select the appropriate transformers, conductors and busbars, taking into account prospective loads. PSASP software is used to calculate short circuit and power flow to check whether the power grid meets the requirements. Finally, the reliability test of the new reliability index to the power network is introduced.
