摘要

負載模型可反映負載功率(有效功率與無效功率)和電壓(大小與頻率)之間的相互關係，電力系統的負載特性對系統負載潮流及穩定度包括暫態穩定度、電壓穩定度及動態穩定度的分析皆有著重大的影響，準確的負載特性將有助於電力工程人員在負載潮流與穩定度之模擬分析。本文首先利用元件聚集法，搜集變電所負載特性及負載組成比例，輸入負載組合程式(LOADSYN)，獲得變電所之負載模型參數，並使用監錄量測法，搜集台電公司近兩年變電所監錄之資料，利用模擬退火法求得近似最佳解或整體最佳解的能力，獲得變電所之負載模型參數。利用元件聚集法與監錄量測法求得之參數，分別模擬其波形並與實際量測之波形作一比較，研究顯示以監錄量測法求得之負載模型參數較為準確。

Load model is representation of the relationship between the power (active and reactive) and bus voltage (magnitude and frequency). Load characteristics of power system have a significant effect on power system analysis of power flow and stability that includes transient stability, voltage stability and dynamic stability. The accurate load characteristics will help engineer to analysis power flow and stability. This paper adopts Component-based Approach construct load models to collect load characteristics and load compositions of substation. In which, the data to be input Load Model Synthesis Computer Software (LOADSYN) for obtain the load model parameters. By using Measurement-based Approach, the recorded data of Taipower in recent two years will be use Simulate Annealing algorithm to find the global or near global optimum solutions for obtain the load model parameters of substations. Besides, this paper uses foregoing obtains parameters to simulate and compare with field measurement. The results show load model parameters that obtain by Measurement-based Approach is better than Component-based Approach.
