中文摘要 | 本文首先依用電之結構及用電之屬性(住宅、商業、工業)將各用電器具 詳加分類,再以一變頻器(將頻率由58.5Hz微調至61.5Hz)及電力分析儀來量測各負 載元件之有效功率與無效功率對頻率之依存度。最後將所量測之頻率相依負載特 性值(dp/df&dq/df),變電所之負載混合百分比,各負載元件之組成百分比與EPRI 設定之電壓對有效及無效功率(dp/dv&dq/dv)之相依參數值輸入至負載組合程式 (LOADSYN)以建立適合於PSS/E動態模擬程式之負載模型。 本文以一三相短路故障來分析不同負載模型對電力系統暫態穩定度之影響,並與 事故記錄比較以確認負載模型是否準確。 |
英文摘要 | In this paper, electric appliances are finely categorizedaccording to power consumption structure. A variable frequency device (frequency being adjusted from 58.5Hz to 61.5Hz)and power demand meter are then used to measure frquency dependence of real and reactive power of all load components.Finally, the measured frequency dependence load characteristics (dp/df & dq/df), substation load mixture percentages, loadcomposition percentages, and dependence of voltage suppliedon the real and reactive power (dp/dv & dq/dv) are fed intoLOADSYN program so as to establish a load model suitable forPSS/E dynamic simulation program. Typical three-phase short-circuit fault is used tosimulate the influnece of various load models on transientstability by PSASP, and field measurements of substationvoltage and real and reactive power are used to confirm theaccuracy of the load model obtained through the LOADSYNprogram. |
