智能型断路器在低压交流微电网的应用探索

Exploration on Application of Intelligent Circuit Breaker in Low-voltage AC Microgrid

以IEEE 2030标准关于微电网规划要求与ABB智能型断路器产品的相关功能进行对比,探索智能型断路器在低压交流微电网中的应用,包括作为微电网PCC点接口设备和接口保护系统及同期重合闸、实现独立运行状态下的功率控制(分级减载)、自适应保护实现选择性保护配合、快速通信功能、监控与电能管理功能等。并结合具体工程案例,介绍智能型断路器在低压交流微电网的应用。

Based on the comparison between microgrid planning requirements of the IEEE 2030 standard and the related functions of ABB intelligent circuit breaker products,the application of intelligent circuit breakers in low-voltage AC microgrids is explored,including acting as a microgrid PCC point interface device and interface protection system, and synchronous re-closure and power control under independent operation(graded load shedding),self-adaptive protection to achieve selective protection coordination,fast communication function,monitoring,power management and other functions. Further,the application of intelligent circuit breakers in low-voltage AC microgrid is introduced in combination with specific project cases.
