固态继电器实现自动有载调压在农电中的应用

Application of Automatic Voltage Regulation with On-load in the Agricultural Power System Based on Solid State Relay

电能质量的主要指标有频率、电压和谐波。由于电力系统中运行方式的千变万化,每个节点电压都不相同,用户对电压的要求也不一样。为此,详细阐述了应用固态继电器实现有载自动调压的原理。此继电器具有调节速度快、冲击电流小、可频繁操作、结构简单、造价低的特点,便于在农电系统的配电变压器中推广应用。

The principle of automatic voltage regulation by using solid state relay is expounded in detail in the paper. It has high regulation speed, and low rush current, and is operated frequently; at the same time its structure is simple and the cost is low, and can be used widely among the distributed transformer.
