谐波和无功功率补偿技术以及智能电网的发展要求功率分解和电流分解理论更加实用有效,针对该问题,本文研究了CPT(Conservative Power Theory)功率分解理论.以CPT理论为依据,将非线性负载电流分解为具有明确物理意义的正交分量,与传统的瞬时无功功率理论相比,更加适用于无功电流和谐波电流的定义以及要求对无功电流、谐波电流和电流中的不平衡分量分别进行精确检测的系统.通过MATLAB仿真和DSP实现,验证了理论分析的正确性和可行性.

With the development of harmonic and power compensation techniques and smart grid, power and current decomposition is required more practical and effective. Aiming at this problem, conservative power theory is researched deeply in this paper. Based on conservative power theory, nonlinear loads current is decomposed into orthogonal terms with definite physical meaning. Compared with traditional instantaneous reactive power theory, CPT is more beneficial to reactive power and harmonic definition. Besides,CPT is more applicable to the system which requests different current terms decomposed separately. The MATLAB simulation and DSP experiment results verify the validity and feasibility of the theory analysis.
