具体实施方式
下面结合附图及具体的实施例对实用新型进行进一步介绍。
如图1~3所示，一种主动配电网中交直流接口换流器的智能控制装置，包括DSP处理器一、DSP处理器二、DSP处理器三和实时仿真器UREP， DSP处理器一、DSP处理器二、DSP处理器三通过I/O口连接到实时仿真器UREP和上位机，实时仿真器UREP通过以太网通信模块连接到上位机， DSP处理器一用于PV控制， DSP处理器二用于PQ控制和DSP处理器三用于V/f控制，实时仿真器UREP中用于动态模拟含交直流接口的主动配电网，包括交直流配电网和交直流接口换流器一次系统模型，交直流接口采用电压源型变换器（VSC），电压源型变换器包括VSC1、VSC2和VSC3三个交直流接口，实时仿真器UREP通过AO输出口和DI输入口与DSP处理器一、DSP处理器二、DSP处理器三的AI输入口和DO输出口进行连接，形成整个系统的闭环控制，即完成半实物结构。
上述的PQ控制的主要作用为改变交直流系统间的功率流动，进而实现潮流优化和提高分布式电源的消纳能力等功能；上述V/f控制可实现故障点下游负荷的不间断供电；上述V/Q控制主要稳定直流系统电压和提供无功补偿，三个DSP处理器根据不同工况自动切换至相应配电网的PQ控制模式、VQ控制模式和V/f控制模式进行控制，并通过上位机对三个DSP处理器进行远程操作，同时还可以对UREP进行监控。
工作过程为：VSC1采用VQ控制，当VSC1所在交流支路发生故障时（如B4），VSC1切换为V/f控制，继续为断点下游支流负荷供电，使之运行在孤岛模式，VSC2则切换为VQ控制，继续为直流侧提供电压支撑及平衡功率流动；含该交直流联络开关的设备还可实现能量调度，将VSC3运行在PQ控制模式，可实现区域1与区域2之间的能量互补，如区域1分布式电源出力较大时，可通过VSC3将多发的能力传输到区域2中，以提高分布式电源的消纳能力和减轻区域2交流馈线的负担。以上过程皆有上位机对智能交直流接口控制器进行操作，通过上位机还可对UREP的动态模型系统进行电能质量监控。
