摘要: |
结合工程实践,建立了网省地全局电网闭环控制仿真系统。介绍该仿真系统的数据流程及功能框图,使用单断面仿真和连续断面仿真两种方式模拟了无控制、独立控制、协调控制等不同控制条件下的电网运行状态变化,研究分析不同的控制条件对系统网损、电压稳定裕度、联络关口无功等指标的影响。仿真结果表明:通过对各级自动电压控制系统控制目标和控制行为的协同,可有效避免控制振荡,消除网间不合理的无功流动。 |

Abstract: |
Combining with engineering practice, this paper develops the closed-loop control simulation system. The data flow and functional diagram of simulation system are introduced. The single section simulation method and continuous section simulation method are used to simulate the running state of power system, with three different control conditions, including no control, independent control and coordinated control. By the contrast analysis, this paper researches the influence of control condition to system loss, voltage stability margin and tie line reactive power. The simulation results indicate that the coordination among multi-level hierarchical control systems can effectively avoid the control oscillation and reduce the irrational reactive power flow between the higher power system and the lower power system. |
