摘要:
为了满足变压器保护可靠性、速动性和灵敏性的要求,以TI公司的DSPF28335为控制核心,编写算法设计变压器的保护装置。以二次谐波制动的方法躲过变压器合闸时的励磁涌流,利用纵联差动保护作为变压器主保护,利用过电流保护作为后备保护。利用MATLAB/Simulink搭建110 kV/11 kV等级的变压器模型,设置相应的故障,在半实物仿真平台RT-LAB上验证保护装置的性能。

Abstract: With a TI Corporation DSPF28335 as the core of control, a transformer protection was designed that meets the needs of selectivity, speed, reliability and sensitivity, clears internal faults by lon-gitudinal differential protection, and uses over-current protection as backup protection. A 110/11 kV transformer model was designed in MATLAB/Simulink. Then, corresponding faults were set to obtain simulation waves and to activate RT-LAB, a real-time simulation platform. With a DSP, hardware for the real-time simulation loop was achieved, and corresponding figures and performance tests of the protection were obtained.
