中文摘要:

直驱风电场在面对次/ 超同步振荡风险时,通常在发生振荡后切除全部风机来保证电网安全。切除整个风场不仅严重破坏风电场的生产运行,对电网也会造成较大冲击,是事态升级后不得已采取的紧急措施。针对以上问题,论文提出一种宽频测量装置辅助的直驱风电场功率调节和切机控制策略,以实现次/ 超同步振荡事故的预警和快速抑制。风电场随时关注区域电网内雷击跳闸等可能诱发振荡的事件。当接收到事件报告后,风电场随即进入预警状态并按照预动作策略调节各风机功率进入低诱发状态,同时宽频测量装置进入紧急状态监测风电场是否发生次/ 超同步振荡。当检测到振荡后,风电场根据各风机与并网点距离和各风机功率计算切机强度指标,对部分风机执行切机策略,以实现振荡消除。论文建立相关仿真算例对控制策略的可行性和有效性进行验证,仿真结果表明所提出的功率调节和切机控制策略实现直驱风电场振荡的抑制,同时避免了风电场切除全部风机,降低了对电网的冲击。

英文摘要:

Direct-drive wind farms usually trip all wind turbines to ensure power grid security when facing sub/ super-synchronous oscillation risks. Tripping the entire wind farm not only seriously damages the production operation of the wind farm, but also causes a large impact on the power grid, which is an emergency measure that has to be taken after the situation escalates. To address this problem, this paper proposes a wide-frequency measurement device assisted power regulation and generator tripping control strategy for direct-drive wind farms, to achieve early warning and rapid suppression of sub/ super-synchronous oscillation accidents. The wind farm pays attention to events such as lightning tripping in the regional power grid that may induce oscillations at any time. When receiving an event report, the wind farm immediately enters a pre-warning state and adjusts the power of each wind turbine according to the pre-action strategy to enter a low-inducing state, while the wide-frequency measurement device enters an emergency state to monitor whether the wind farm has sub/ super-synchronous oscillations. When oscillations are detected, the wind farm defines the tripping intensity index according to the distance between each wind turbine and the grid-connected point and the power of each wind turbine, and executes the tripping strategy for some wind turbines to achieve oscillation elimination. This paper establishes relevant simulation examples to verify the feasibility and effectiveness of the control strategy. The simulation results show that the proposed power regulation and generator tripping control strategy achieves the suppression of oscillations in direct-drive wind farms, while avoiding the tripping of all wind turbines in the wind farm, reducing the impact on the power grid.
