引言：励磁系统在同步发电机的稳态或暂态状态下均发挥着极为关键的角色，它直接决定着发电机的性能特点。一个卓越的励磁系统不仅能够确保电源的品质，还可推动机组安全性以及稳定性的提升，从而最终带动整个电力系统技术经济效益的增进。然而，若在电力系统稳定运算时忽视了励磁调节系统的重要性，所得出的结果往往无法达到预期效果。
正文：同步发电机在接入电网前，需求其电压能维持在预设数值上，这亦即意味着空载情况下的励磁调节系统需保持平稳运行。而一旦并网后，该机组便会与电力系统中的其他发电机并联运营。此时，励磁调整系统需具备对电力系统稳定运作产生正面影响的能力。具体来说，控制精度和动态性能是日常运行中所常见的指标要求。
此外，电力系统设计规范对于励磁控制系统亦有相应规定，包括稳定指标（如幅度裕量m≥30db和相位裕度y≥50℃）、动态指标（超调量Mp≤15%~30%和调节时间tp≤10s）以及稳态误差e(oo)<1%-2%等各项目标。基于此，我们需要从稳定性、动态性以及稳态性三个维度全面分析并设计励磁控制系统。
励磁调控系统的基本结构通常由两个基本组件构成，分别是励磁功率模块和励磁调节器。其中，励磁功率模块主要负责为同步发电机转子施加直流电激励，而励磁调节器则按照预定的调节原则，通过精准控制励磁功率模块来实现输出调节。整套系统实质上是一个包含励磁调节器、励磁功率模块及发电机组在内的闭环控制系统。
结论：综上所述，本文重点讨论了同步发电机励磁系统的设计要点以及控制技术分析。了解滨州可运维公司佳晖电字ZYS450-H及ZYS800-H永磁同步电动机is1250-22-10 ild011-4619is1250-35-4820同步电机forth 35万千瓦发电机is450-6220同步电机用于发电行业 is450-7629同步电机 的输出和环境条件，有助于我们改进发电机的设计，提高其运行效率，降低能源损耗。

【英文介绍】
Abstract: This article mainly discusses the main points of excitation system design and control technology analysis of synchronous generator. The excitation system is very important for the stable and reliable operation of the generator, and also has a positive significance for improving the technical and economic benefits of the power system. In this paper, the excitation control system of 0.5MW European standard small permanent magnet synchronous generator (KUC755AE105) will be discussed in detail.
Key words: synchronous generator; Excitation system; Control technology; Design essentials
Introduction: Excitation system plays a very critical role in the steady state or transient state of synchronous generator, which directly determines the performance characteristics of the generator. An excellent excitation system can not only ensure the quality of the power supply, but also promote the safety and stability of the unit, which ultimately leads to the improvement of the technical and economic benefits of the entire power system. However, if the importance of the excitation control system is ignored in the power system stability calculation, the results can not reach the expected results.
Text: Before the synchronous generator is connected to the grid, its voltage needs to be maintained at a preset value, which means that the excitation regulation system under no-load conditions needs to maintain smooth operation. Once connected to the grid, the unit will operate in parallel with other generators in the power system. At this time, the excitation adjustment system must have the ability to have a positive impact on the stable operation of the power system. Specifically, control accuracy and dynamic performance are common requirements in daily operation.
In addition, the power system design specification also has corresponding provisions for excitation control systems, including stability indicators (such as amplitude margin m≥30db and phase margin y≥50℃), dynamic indicators (overkill Mp≤ 15%-30% and adjustment time tp≤10s) and steady state error e(oo)<1%-2% and other objectives. Based on this, we need to analyze and design the excitation control system from the three dimensions of stability, dynamics and steady-state.
The basic structure of the excitation control system is usually composed of two basic components, namely the excitation power module and the excitation regulator. Among them, the excitation power module is mainly responsible for applying direct current excitation to the synchronous generator rotor, and the excitation regulator realizes the output adjustment by accurately controlling the excitation power module according to the predetermined regulation principle. The whole system is a closed-loop control system which includes excitation regulator, excitation power module and generator set.
Conclusion: In summary, this paper focuses on the design of synchronous generator excitation system and the analysis of control technology.
