【摘要】：配电网规划是电力系统研究领域中的一个重要内容,为了保证电网改造的合理性和电网运行的安全性和经济性,提高配电网供电质量,必须对其进行科学的优化规划。桥头镇位于东莞市东部,地理位置优越,配套设施完善,交通便利,桥头镇定位为全国综合实力千强镇和中国荷花名镇,经济建设和文化事业的持续发展,镇内大力发展工业园区、房地产业及第三产业的建设,绿色节能高效的电量需求跳跃式增长,对电网供电能力的要求不断提高,中低压配电网规划工作显得格外重要。本论文首先通过对东莞桥头镇社会经济发展情况的研究,详细分析东莞桥头镇的历史用电需求、电源现状、中低配电网现状,总结东莞市桥头镇中低配电网运行存在的主要问题,提出问题的成因以及规划解决的思路。其次,基于东莞市桥头镇近两年的负荷报装数据,参考当地经济发展规划、重点区域规划和重大项目建设进度。采用报装负荷法和年增长率与最大负荷利用小时数相结合的预测方法,对桥头镇总量负荷进行预测,对逐年桥头镇负荷水平进行预测,通过供电区分类对预测结果进行校验,得到出未来年桥头镇负荷及电量数据。再次,结合上级变电站规划结果和供电范围,拟出了“十三五”期间新出线路规划方案和中低压配电网规划方案,并对中低压规划方案进行分析,得到桥头镇2015年至2020年中低压配电网项目规划的重点。最后,根据桥头镇中低配电网改造及基建项目进度、建设规模及投资单价,估算出“十三五”期间桥头镇中低配电网总投资,分析评估桥头镇中低配电网现状存在问题的解决程度及可靠性和线损率指标。
[Abstract]:Distribution network planning is an important content in the field of power system research. In order to ensure the rationality of power network transformation and the safety and economy of power network operation and improve the power supply quality of distribution network, it is necessary to carry out scientific optimization planning. Qiaotou Town is located in the east of Dongguan City, with excellent geographical location, perfect supporting facilities and convenient transportation. Qiaotou Town has been positioned as one of the most powerful towns in the country with comprehensive strength and famous lotus towns in China, with the sustained development of economic construction and cultural undertakings. It is very important to develop the industrial park, the real estate industry and the third industry in the town, the green energy saving and high efficiency electricity demand leaps and bounds, the demand for the power supply ability of the power network is raised constantly, the planning work of the medium and low voltage distribution network is especially important. Firstly, through the research on the social and economic development of Qiaotou Town in Dongguan, this paper analyzes in detail the historical demand for electricity, the current situation of power supply, and the present situation of middle and low distribution network in Dongguan Qiaotou Town. This paper summarizes the main problems existing in the operation of middle and low distribution network in Qiaotou Town, Dongguan City, and puts forward the causes of the problems and the ideas of planning and solving. Secondly, based on the load data of Qiaotou Town in Dongguan City in the past two years, we refer to the local economic development plan, the key regional planning and the progress of major project construction. By using the forecasting method of load reporting and loading and combining the annual growth rate with the hours of maximum load utilization, the total load of Qiaotou Town is forecasted, the load level of Qiaotou Town is forecasted year by year, and the forecasting results are verified by the classification of power supply area. Get the data of load and electric quantity of bridgehead town in the coming year. Thirdly, according to the results of substation planning and the power supply range, the new line planning scheme and the middle and low voltage distribution network planning plan during the 13th Five-Year Plan period are drawn up, and the middle and low voltage planning schemes are analyzed. Qiaotou Town from 2015 to 2020 medium-low-voltage distribution network project planning focus. Finally, according to the progress of the middle and low distribution network reconstruction and the capital construction project, the scale of construction and the unit price of investment, the total investment in the middle and low distribution network of Qiaotou Town during the 13th Five-Year Plan period is estimated. This paper analyzes and evaluates the degree of solution, reliability and line loss rate index of the existing problems in the middle and low distribution network of Qiaotou Town.
