    摘要:

    当特高压直流严重故障时电网会采取紧急切负荷措施,为了实现切负荷时的精准,本文提出了基于用户可中断负荷的实时负荷控制决策技术,研究了控制决策过程中涉及的快速响应、精准控制、稳控保障等关键技术,设计了用户动态序位表、决策准备、负荷循环补备、失效开关清单等决策中使用的机制,最后模拟了实时控制决策的应用场景。本文提出的实时负荷控制决策技术已经在江苏电网大规模源网荷友好互动系统中应用,实现了在接收切负荷指令后对用户可中断负荷实时精准控制。

    Abstract:

    When serious HVDC transmission fault happens, emergency load shedding measures will be taken. In order to achieve the precise load shedding, it proposes a real-time load control decision technology based on user’s interruptible load. Some key technologies involved in the process of control decision are studied just like quick response, precise control, stability control security. Designed the mechanism used in the decision such as user dynamic sequence table, decision preparation, load cycle supplement, failure switch list and so on. Finally, the application scene of real-time control decision is simulated. The real-time control decision technology proposed in this paper has been applied in the large scale supply and demand friendly interactive system, and has realized real-time precision control ability to user’s interrupt after receiving the load shedding instruction.
