中文摘要 | 近年來由於電力電子科技的進步及節約能源觀念的推廣, 變頻式中、小型感應電 動機在近幾年已被大量的採用在各式機電產品。在國外亦有舊型火力電廠翻新後採用變頻式 感應電動機之實例。雖然,目前國內火力機組大多使用在中、基載情況下,但面對尖、離峰 用電差距地擴大及大規模的建廠計畫,未來供電情況將有改變的可能。因此針對未來大型火 力建廠計畫,宜未雨綢繆及早對採用變頻式感應電動機之可靠性及經濟效益進行評估。 因此,本文主要目的即是火力電廠之電動機以變頻式感應電動機取代之經濟效期做一適當之 評估。並且,將討論變頻式驅動器和相關之電動機規格與標準。同時,變頻式驅動器和電動 機的選擇及其相容性亦將詳細描述於本文。 |
英文摘要 | Recently, the highly development of the power relectonics technology have made the rapid advances of adjustable speed drives for medium and large induction motors. The adjustable speed drives have been employed in several power plants in USA for improving system performance and reliability, minimizing equipment stress, and reducing system operating costs. Also, the examples for control of power plant and district heating drives with adjustable speed drives have been found in Finaland. However, in Taiwan, the adjustable speed drives have not been used in the gas-, oil-, or coal-fired plants. Inorder to understand the benefits for using the adjustable speed drives in induction motors, the economic evaluations will be made before the setup of a power plant. The main purpose of this paper is to evaluate the economic benefits of retrofitting the utility power plant motors with adjustable speed drives. The specifications and test standards of the induction motors and the adjustable speed drives will also be discussed. Furthermore, the selection criterion and the compatibility for the adjustable speed drives and induction motors will be both presented in this paper. |
