自动发电控制(automatic generation control,AGC)是电网调度自动化系统中的一项重要功能,在统一调频控制和电力现货市场环境下AGC控制功能重要性愈加凸显。本文研究提出了基于实时仿真的网级和省级AGC联合闭环测试方案,进而研究开发了实时仿真与网省AGC异构系统的通信交互接口和实时闭环测试技术,提出了多GTNET卡并联同步以及“单端接口、数据转发”等数据交互接口方法,解决了网省AGC仿真联合实时闭环测试中的海量实时数据交互问题。最后通过接口测试验证了多GTNET卡并联同步高速通信能力及其接口延时特性。

Automatic generation control(AGC)is an important function in the power system dispatching automation system.The importance of AGC control function is becoming more and more prominent in the unified frequency control and electricity spot market environment.A grid level and provincial level AGC joint closed-loop testing scheme based on real-time simulation is proposed in this paper.Then the communication interface between real-time simulation platform and heterogeneous system of grid-province AGC as well as the real-time closed testing technologies are researched and developed.The data interface methods such as parallel synchronization of multi-GTNET cards and"single terminal interface-data forwarding"are proposed to solve the problem of massive real-time interface data in the grid-province AGC joint closed-loop testing.Finally,the parallel synchronous high-speed communication ability and interface delay characteristics of multi-GTNET cards are verified through the interface test case.
