UNITROL-1020 基于先进的微处理器技术和IGBT半导体器件

小型间接励磁系统的作用是在正常运行的条件下供给发电机励磁电流，UNITROL-1020并根据发电机负载情况做相应的调整，以维持发电机端电压或电网某点电压为一定水平。当电力系统发生短路故障或其他原因使系统电压严重下降时，对发电机进行强行励磁，以提高电力系统的稳定性。当发电机突然甩负荷时，实行强行减磁，以限制发电机端电压的过度增高。

ABB的UNITROL 1010是一款功能强大且紧凑的间接励磁系统，UNITROL-1020适用于中小型同步发电机和工业机器，经过DNV和UL标准的全面认证。其基于先进的微处理器技术和IGBT半导体器件，可在严苛条件和不同温度范围下进行高性能工作，并且完全符合DNV和UL标准。

小型间接励磁系统的工作原理主要是通过控制励磁电流来调节发电机的输出电压。这种系统通常包含一个电压调节器，UNITROL-1020调节器能够检测发电机输出电压的变化，并根据这些变化调整励磁电流的大小，以保持输出电压的稳定。

具体来说，当发电机输出电压升高时，调节器会减少励磁电流，降低发电机磁场强度，从而降低输出电压。相反，当发电机输出电压降低时，调节器会增加励磁电流，增强发电机磁场强度，从而提高输出电压。

此外，小型间接励磁系统通常采用电子控制技术实现电压调节，具有快速响应和较高控制精度的特点。同时，由于系统结构简单、可靠性高，因此在中小型发电机组和工业设备中得到广泛应用。

The role of the small indirect excitation system is to supply the generator excitation current under normal operating conditions, and the UNITROL-1020 makes corresponding adjustments according to the generator load to maintain the generator terminal voltage or a certain point of the grid voltage at a certain level. When the power system short-circuit fault or other reasons make the system voltage seriously drop, the generator is forcibly excited to improve the stability of the power system. When the generator suddenly dumps the load, the forced demagnetizing is implemented to limit the excessive increase of the generator terminal voltage.

ABB’s UNITROL 1010 is a powerful and compact indirect excitation system, the UnitROL-1020 is suitable for small and medium-sized synchronous generators and industrial machines, fully certified to DNV and UL standards. It is based on advanced microprocessor technology and IGBT semiconductor devices for high performance in harsh conditions and different temperature ranges, and is fully compliant with DNV and UL standards.

The working principle of the small indirect excitation system is to regulate the output voltage of the generator by controlling the excitation current. This system usually includes a voltage regulator, the UNITROL-1020 regulator can detect changes in the output voltage of the generator and adjust the size of the excitation current according to these changes to keep the output voltage stable.

Specifically, when the generator output voltage rises, the regulator reduces the excitation current and reduces the generator magnetic field strength, thereby reducing the output voltage. In contrast, when the generator output voltage is reduced, the regulator will increase the excitation current, enhance the generator magnetic field strength, and thus increase the output voltage.

In addition, the small indirect excitation system usually uses electronic control technology to achieve voltage regulation, which has the characteristics of fast response and high control accuracy. At the same time, because of the simple structure and high reliability of the system, it is widely used in small and medium-sized generator sets and industrial equipment.
