【摘要】：隨著國家經(jīng)濟的快速發(fā)展和人民生活水平的提高,人們用電需求日益增長,同時對供電質量和供電可靠性提出了更高的要求。由于負荷的不斷增加,以及電源的大幅增加,對電網(wǎng)要求也要改變。 為開發(fā)某一中等城市，現(xiàn)要構建一個具有10至15年遠景規(guī)劃的電力網(wǎng)，全面負責本城市的供電。結合該市的遠景規(guī)劃設想和地理位置，根據(jù)該城市的負荷情況，設計220kV和110kV的電力網(wǎng)。為了使電網(wǎng)能夠穩(wěn)定可靠經(jīng)濟的運行，本設計對該城市的電力電量平衡，無功功率的驗算，看它是否符合要求，進行優(yōu)化。在考慮遠景負荷下，選擇合適的變壓器、導體和母線。應用PSASP軟件對該電網(wǎng)短路計算、潮流的計算，，檢驗電網(wǎng)是否符合要求。最后介紹新的可靠性指標對電網(wǎng)的可靠性檢驗。
[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.
