摘要

针对粒子群优化（particle swarm optimization

PSO）算法存在搜索能力不足和局部收敛的问题，提出了一种融合海鸥优化算法（seagull optimization algorithm

SOA）与PSO算法相结合的火电机组一次调频参数辨识方法。该算法采用自适应非线性惯性权重，以平衡算法局部与全局搜索能力；采取非线性飞行时间系数，以优化算法收敛速度；采用融合海鸥算法螺旋攻击行为的方式对适应度较差的粒子进行优化处理，增强算法跳出局部最优的能力，有效避免算法局部收敛问题。针对机组电液伺服系统的PID参数辨识进行仿真验证，并与传统PSO算法进行比较，针对汽轮机3个容积时间常数辨识进行试验验证，并应用于火电机组一次调频仿真建模，结果表明该方法适用于火电机组一次调频参数辨识，且辨识精度更高，算法更为稳定，收敛速度也更快。

Abstract

To address the issue of insufficient search ability and local convergence of particle swarm optimization(PSO) algorithm

in this paper we propose a primary frequency modulation parameter identification method for thermal power units combining seagull optimization algorithm (SOA) and PSO algorithm. This method utilizes adaptive nonlinear inertial weights to balance the local and global search capabilities of the algorithm. The nonlinear time-of-flight coefficient is adopted to optimize the convergence speed of the algorithm. The spiral attack behavior of the seagull algorithm is utilized to optimize the particles with poor adaptability

thereby enhancing the ability of the algorithm to jump out of the local optimization and effectively avoiding the problem of local convergence of the algorithm. The PID parameter identification of the electro-hydraulic servo system of the unit is simulated

verified

and compared with the traditional PSO algorithm. The identification of the three volumetric time constants of the steam turbine is validated through the experiment. The method is applied to the primary frequency regulation simulation modeling of thermal power units. The results indicate that the method is suitable for the identification of primary frequency regulation parameters of thermal power units

with higher identification accuracy

greater algorithm stability

and faster convergence speed.
