摘要
变速恒频电源数字控制技术以 DSP作为控制核心 ,主要实现对变换器的控制和发电系统电压调节 ,同时也实现了系统保护功能。数字变换器控制方案采取了十三块波开关点预置最优 SP-WM控制和动态波形的校正技术 ,明显改善了变换器的性能。数字电压调节器采用了模糊 -滤波控制算法 ,并采用软起动技术、最大励磁电流限制技术及逆磁电路 ,在保证系统具有良好稳态性能的前提下 ,使加卸载过渡过程时间比模拟电压调节器有明显缩短。最后通过系统实验验证了
Digital control of VSCF power system, which uses DSP as its control core, realizes the control of inverter and voltage regulator, as well as the system protection. Control scheme of digital inverter uses 13 wave switching node preset optimum SPWM, and the dynamic waveform correcting technology. Its inverter performance is greatly improved. Fuzzy filter algorithm and technology of soft starting, maximum exciting current restriction, negative field forcing are used in digital voltage regulator. The perfect steady and dynamic performance of the system is verified by experiments.
