摘要
针对复杂电网中确定配电网是否经济运行的难题,给出了以经济运行负荷和经济运行时间来划分配电网经济运行区域的两种解析方法,阐述了各类运行区域的特点,分析了配电网技术改造的要点。并分析对比了两种方法,提出了以经济运行时间确定配电网经济运行区域更为准确,为降损改造提供了依据。最后通过实际线路计算验证了该方法的准确性以及降损的可行性。
To determine whether distribution network is optimal in complex distribution network is difficult. Presenting two theoretical calculation methods for dividing economic area with economic operation load or economic operation time. Described the characteristics of various types of operation area and analysis of the main points of distribution network transformation. Analysis and comparison of the two methods, proposed economic operation time is more accurate for determining whether distribution network is optimal. It has practical significance to improve the economic operation of distribution network. The actual line computation confirms each kind of analysis or computation method accuracy and usability.
