新能源远距离送出系统的短路比较低时,容易引发振荡和过电压等问题,提升送端电网的电网强度存在迫切需求。鉴于调相机在动态无功支撑方面的优势,工业界普遍采取加装调相机的措施以提升大型新能源基地的送出能力。然而,调相机本质上是同步机,在短路比较低且新能源控制配合不恰当时存在暂态功角失稳风险,这一潜在问题尚未引起工业界的足够重视。为此,首先解析了新能源送出系统调相机的功角特性,分析了调相机暂态功角失稳机理。其次,提出了量化调相机同步稳定性的新能源等效容量折算系数和系统的临界短路比条件。进一步,分析了影响调相机功角稳定水平的关键因素,为后续提高调相机同步稳定裕度的协调控制策略提供理论基础。仿真算例验证了所提稳定机理和影响因素的有效性。
When the short-circuit ratio of the renewable energy long-distance transmission system is relatively low
it is easy to cause the problems such as oscillation and overvoltage. So there is an urgent need to improve the power grid strength of the sending-end power grid. In view of the advantages of the synchronous condenser (SC) in the dynamic reactive power support
the industry generally takes measures to install the SC to improve the transmission capacity of large-scale renewable energy bases. However
the SC is a synchronous generator intrinsically
therefore there is a risk of transient power angle instability especially when the short-circuit ratio is low and the control strategies of renewable energy do not match well. This potential problem has not attracted enough attention from the industry. To this end
the power angle characteristics of the SC of the renewable energy transmission system are firstly analyzed
and the transient power angle instability mechanism of the SC is analyzed. Secondly
the equivalent convert coefficient of the renewable energy capacity and the critical short-circuit ratio condition of the system are proposed to quantify the synchronization stability of the SC. Furthermore
the key factors affecting the power angle stability of the SC are analyzed
which provides a theoretical basis for the subsequent coordinated control strategy to improve the synchronization stability margin of the SC. Simulation examples verify the effectiveness of the proposed stabilization mechanism and influencing factors.
