| 摘要: |
| 特高压直流输电工程直流输送功率按调度编制的日功率计划曲线运行，功率计划的下发和执行直接影响到直流系统的稳定运行。在深入研究104/101远动规约及特高压直流输电工程应用的基础上，对直流工程远动系统及自动化监控系统SCADA进行了功能扩展，在远动系统中实现了基于IEC60870-5-104/101的功率计划的调度实时远传、接收、解析、显示及存储。在自动化监控系统SCADA中实现了自动功率控制功能，向直流工程控制系统下发功率计划值，具备较高的实时性和可靠性。功率计划的实时传输和自动功率控制的实现能够有效地提高电网调度部门及换流站运行人员的工作效率，对进一步提高电网安全运行水平具有重要意义。 |

| Abstract: |
| The DC transmission power of UHVDC transmission project is set according to the daily power plan made by dispatching system, and the sending and carrying out of the power plan directly influence the stability of the DC system. Based on the in-depth study of IEC60870-5-104/101 and the engineering application of UHVDC transmission project, a function extension of the RCI system and SCADA system are made, a real time transmission, receiving, analysis, display and storing of the power plan are realized based on IEC60870-5-104/101. The automatic power control is realized in the SCADA system, which sends power value automatically to the control systems with high instantaneity and responsibility. The transmission of the power plan and the realization of the automatic power control could improve the efficiency of operators, and there is significance on improving grid security. |
