摘要：

随着风电并网容量的增加,导致系统惯量支撑能力不足,电网频率失稳等问题日益显著,虚拟同步发电机技术模拟同步发电机运行特性成为一种有效的解决方案。以风电场主流机型之一的直驱永磁风电机组为研究对象,在并网控制中引入虚拟同步控制策略,提高直驱永磁风电机组的等效惯量,使其向电网输送平滑功率。并利用机组自身超速和变桨协调控制提供备用容量,通过虚拟同步发电机的惯量响应控制环节增发有功出力,从而提升系统一次调频能力。仿真结果表明,所提出的协调控制策略能够充分利用风电机组自身减载运行和虚拟同步发电机技术,有效提升并网系统的频率稳定和惯性支撑效果,有利于电力系统的安全稳定运行。

Abstract:

With the increase of wind power grid-connected capacity, the system inertia support capacity is insufficient, and the grid frequency instability is becoming more and more obvious. The virtual synchronous generator technology simulates the synchronous generator operation characteristics and becomes an effective solution. the direct-drive permanent magnet wind turbine of one of the mainstream models of wind farms as the research object is taken, and introduces the virtual synchronous control strategy in the grid-connected control to improve the equivalent inertia of the direct-drive permanent magnet wind turbine to deliver smooth power to the grid. And use the unit's own overspeed and pitch coordinated control to provide spare capacity, through the virtual synchronous generator's inertia response control link to increase the active output to improve the system’s primary frequency modulation capability. The simulation results show that the coordinated control strategy proposed here can make full use of wind turbine’s own load shedding operation and virtual synchronous generator technology, effectively improve the frequency stability and inertial support effect of the grid-connected system, which is conducive to the safe and stable operation of the power system.

Key words: Direct drive permanent magnet wind turbine, virtual synchronization control, spare capacity, inertia, primary frequency modulation
