摘要

火电机组一次调频和二次调频控制成本差异较大，需要对其控制性能分别评价，为合理补偿或付费提供依据。一次和二次调频响应功率是机组控制性能评价的基础参量，但两者彼此交织于机端有功功率而无法直接使用，导致分别评价缺乏依据。基于数值解析方法得到的一次和二次调频功率时间序列的时频差异，利用惯性比例-时延参量最小二乘拟合和Hodrick-Prescott趋势特征提取函数，提出了一种迭代分离算法；采用系统频率响应模型的响应功率和二次调频指令分别作为一次和二次调频功率迭代初值，可进一步提高数据剥离效果。仿真算例验证了所提方法的有效性与可行性。

Abstract

There is a great difference between control costs of primary frequency regulation and secondary frequency regulation of thermal units

so it is necessary to respectively evaluate their control performance to provide a basis for reasonable compensation or payment. Primary and secondary frequency regulation response power are the basic parameters for the control performance evaluation of the units

but they are interwoven with the active power of the unit and cannot be used directly

resulting in the lack of the evaluation basis. Based on the time-frequency difference of the primary and secondary frequency regulation power time series obtained by the numerical analysis method

an iterative separation algorithm is proposed by the least square fitting of inertia proportional and delay parameter and Hodrick-Prescott trend feature extraction function. The response power of the system frequency response model and the secondary frequency regulation instruction are used as the initial iteration values of the primary and secondary frequency regulation power

respectively

which can further improve the data separation effect. The effectiveness and feasibility of the proposed method are verified by a simulation case.
