| 中文摘要 | 本文依據靈敏矩陣M及分支電流法,而提出一個析弱質網目工業配電系統負載潮 流的方法。其組成靈敏矩陣M的新演算法具有直接、簡單的特性,且M矩陣的元 素質能隨系統PV母線數目的改變而作修正。在每次疊代時對迴路電流修正量所引 起的母線電壓變動量亦用來修正母線的電壓,因此運萛效率高。在執行負載潮流 運算時,其疊代次數雖大於預估分枝功率法,但運算時間則較少。最後以17、26、 38及71個母線的4個模擬系統作模擬,印證平方法的功能;例如一個71個母線 的系統,其運算時間僅為分枝功率法的62.3﹪。 |
| 英文摘要 | A new approach based on building and estimating branch currents to solve the load flow of the weakly meshed industrial distribution systems is presented. The new algorithm for developing sensitivity matrix M is direct, simple, and the values of each element of M matrix can be updated while the number of PV buses of system is changing. In each iteration, the bus voltage variations resulted from loop current corrections are also used to update the bus voltages, so the computation efficiency is very high. Although, the iteration number of the proposed method is larger than the method of branch power estimation, its operation time is less. In order to demonstrate the performance of this method, simulation has been carried out for 17, 26, 38, and 71 bus systems. As an example, the operation time for 71 bus system is only 63.2% of the other method. |
