机电暂态仿真是大电网分析的重要工具。现有电力电子设备的机电暂态模型一般呈现理想电流源特性,无法体现设备自身稳定性及能力约束对于系统暂态特性的影响。在电力电子化电力系统背景下,以上不足降低了仿真准确性,制约了电网运行极限制定与新能源送出能力。文中基于旋转坐标系推导了静止无功发生器及控制系统的标幺化数学模型,并建立了对应的机电暂态模型。在建模精度与电磁暂态模型一致的前提下,通过模态分析法对比了机电暂态仿真与电磁暂态仿真的主要差异,揭示了机电暂态仿真的能力边界与适用范围。结果表明,机电暂态仿真能够揭示与工频能量流有关的功角、频率、电压稳定特性,而不能反映与电网动态强相关的谐振或者宽频振荡特性。
Electromechanical transient simulation is an important tool for large-scale power system analysis. Existing electromechanical transient models for power electronic equipment generally have ideal characteristics of current source
which cannot reflect the impact of equipment stability and capacity constraints on system transient characteristics. In the background of power electronics dominated power systems
the above deficiencies reduce the simulation accuracy
which restricts the determination of power grid operation limit and renewable energy transmission capacity. In this paper
the unitary mathematical model and control system of static var generator (SVG) is derived based on the rotating coordinate frame and the corresponding electromechanical transient model is established. On the premise that the modeling accuracy is consistent with the electromagnetic transient model
the main differences between electromechanical transient simulation and electromagnetic transient simulation are compared based on the mode analysis method
which reveals the capability boundary and applicable scope of the electromagnetic transient simulation. The results show that the electromechanical transient simulation can reveal the power angle
frequency
and voltage stability characteristics related to fundamental-frequency power energy flow
but cannot reflect the resonance or broadband oscillation characteristics strongly related to power grid dynamics.
