Excitation system is an indispensable part of power plant equipment. The excitation system includes an exciting power supply and an exciting device, wherein the main body of the exciting power supply is an exciter or an exciting transformer; According to different specifications, models and use requirements, the excitation device is composed of adjustment screen, control screen, magnetic screen and rectifier screen.

The use of the excitation device is to maintain the terminal voltage of the synchronous generator at a given level when the power system is working normally, and at the same time, it also has the function of forced magnetization, magnetization and magnetization. For the excitation transformer as the excitation power supply also has the rectification function. The excitation device can be supplied separately or as a power generation equipment.

Small and medium-sized hydraulic power generation equipment has implemented the export product quality licensing system, and products without export quality licenses are not allowed to export.

Application field

With the continuous increase of generator capacity and power grid, power systems and generator sets require excitation systems to have better control and regulation performance, more and more flexible control, restriction, alarm and other additional functions. In order to meet the above requirements, the microcomputer controlled digital excitation regulator came into being. The wide application of microcomputer excitation regulator greatly improves the safety, reliability and economic benefit of power plant production. The majority of small and medium-sized unit users are also in urgent need of a cheap, excellent performance, simple structure, easy to master, high reliability of the excitation regulator.

Because the design parameters of the excitation device are closely related to the parameters of the synchronous generator and the excitation power supply, the user who orders the excitation device separately should provide or fill in the technical parameters of the power generation equipment used with the excitation device, such as the synchronous generator and the excitation power supply, to ensure the uniform compatibility and performance of the product.

The excitation device should be installed indoors according to the regulations, so its use of ambient temperature, relative humidity, altitude and so on have certain requirements. Attention should be paid to transportation, storage and use. For the special requirements of performance and conditions of use, the user should be clearly stated at the time of signing.

励磁系统是电站设备中不可缺少的部分。励磁系统包括励磁电源和励磁装置，其中励磁电源的主体是励磁机或励磁变压器；励磁装置则根据不同的规格、型号和使用要求，分别由调节屏、控制屏、灭磁屏和整流屏几部分组合而成。

励磁装置的使用，是当电力系统正常工作的情况下，维持同步发电机机端电压于一给定的水平上，同时，还具有强行增磁、减磁和灭磁功能。对于采用励磁变压器作为励磁电源的还具有整流功能。励磁装置可以单独提供，亦可作为发电设备配套供应。

中小型水利发电设备已实施出口产品质量许可制度，未取得出口质量许可证的产品不准出口。

应用领域

随着发电机容量及电网的不断增大，电力系统及发电机组要求励磁系统有更好控制调节性能，更多和更灵活的控制、限制、报警等附加功能。为满足上述要求，微机控制的数字式励磁调节器应运而生。微机励磁调节器的广泛应用，极大地提高了电厂生产的安全可靠性和经济效益。广大中小型机组用户也迫切需要一种价格便宜，性能优良，结构简单，易掌握，可靠性高的励磁调节器。

由于励磁装置的设计参数与同步发电机、励磁电源的参数密切相关，所以单独订购励磁装置的用户，应提供或填写与励磁装置配套使用的发电设备，如同步发电机、励磁电源等的技术参数，以保证产品的统一配套性和使用性能。

励磁装置，按规定应装在室内，所以它的使用环境温度，相对湿度、海拔高度等有一定的要求。在运输、保存和使用时应予以注意。对于性能及使用条件等方面的特殊要求，用户应在签约时明确提出。
