摘要
同步发电机的电能输送给广大的用电负载,同步发电机与电网大系统进行并列是一项非常复杂关键的任务。介绍了同步发电机并列的条件及传统并列方法的缺陷,为了使同步发电机在实验室条件下准确、快速的与电网大系统并列,对传统的并列方式进行了相应改进,变传统的离散式调节为集中式调节,减少了并列的负载性。实验证明改进后的并列方式更有利于发电机的并列,提高了并列的准确性、快速性和安全性。
Electricity from synchronous generators is tran-smitted to a number of electric loads, and the paralleling of the synchronous generators with the power grid is often a very comphcated key task. This paper firstly introduces the conditions for the paralleling of synchronous generators, pointing out flaws in the traditional paralleling method. For synchronous generators to parallel with the large power grid rapidly and accurately under the lab conditions, adequate innovations have been made on the traditional parallel method accordingly, with the discrete regulation changed into the cenlralized one to reduce the paralleling load. The experiments have proved that the innovated parallel method is more convenient for paralleling of synchronous generators with accuracy, speed and safety increased.
