摘要

异步联网方式下的中国西南电网转动惯量显著减小，频率调节特性发生深刻变化，对自动发电控制（AGC）的动态品质要求更高。首先，利用离散傅里叶变换分析了区域控制偏差（ACE）的频域特性。然后，结合中国西南电网高比例水电、大规模外送的显著特征，分析了有功功率控制面临的新问题，建立了维持省级电网控制区有功功率平衡和电网频率稳定性的数学模型。提出了基于2层数字低通滤波的水、火电机组有功功率调节量分离算法，时间维度上实现不同响应时间和跟踪周期的水、火电机组互补协调控制。进而，通过考虑电网频率、ACE以及送出断面功率控制要求，空间维度上动态调整不同地理位置机组群的调用顺序和有功功率调节范围。最后，基于电力系统全过程动态仿真程序（PSD-FDS）验证了所提方法的有效性。

Abstract

The rotational inertia of the Southwest Power Grid of China is significantly reduced in the asynchronous interconnection mode. And the characteristics of frequency regulation have changed profoundly. These require higher dynamic quality for the automatic generation control (AGC). Firstly

the discrete Fourier transform (DFT) is used to analyze the frequency-domain characteristics of area control error (ACE). Secondly

combined with the salient features of high-proportion hydropower and large-scale outgoing transmission in Southwest Power Grid of China

the new problems faced by active power control are analyzed to establish mathematical models for maintaining active power balance in the control area of provincial power grid and frequency stability. An active power regulation capacity separation algorithm for hydropower and thermal power units based on a two-level digital low-pass filter is proposed to achieve complementary and coordinated control of hydropower and thermal power units with different response time and tracking periods in the time dimension. Furthermore

the calling sequence and regulation of active power range of the unit groups at different geographic locations are dynamically regulated in space dimension by considering the grid frequency，ACE and the power control requirements of the sending cross section. Finally

the effectiveness of the proposed method is verified based on the power system full-dynamic simulation program in power system department software package （PSD-FDS）.
