Adaptability analysis of current diffrerential protection for linces of doubling-fed induction generator station connection to flexible-direct grid

IET conference proceedings. (2022)

B. Chen Xi Dong H. Wang Yu-Mei Dai Changbao Deng

In the Zhangbei Flexible-DC Grid Demonstration Project, both ends of the connecting line between the remote new energy station and the flexible and direct power grid are systems containing power electronic devices, which have obvious weak feed characteristics and aperiodic components during faults, which brings new challenges to line protection. In this paper, the characteristics of the fault current of the Doubling-Fed Induction Generator (DFIG) sending line and the AC line of Modular Multilevel Converter(MMC) sending end are analyzed separately, combined with the protection principle of the current differential, the adaptability of the current differential is studied, and the conclusions are drawn: 1. When the short-circuit capacity on both sides of the line has a large difference and a serious fault occurs, the current differential protection can operate reliably; 2. When the short-circuit capacity on both sides of the line is similar, under a serious fault, due to the influence of the aperiodic component of DFIG, the current differential protection may not act; 3. The weak feed-in characteristics of the double-ended system will lead to a decrease in the sensitivity of the protection. At last, the system model is built, and the simulation results verify the conclusion of the theoretical analysis.

Realization of dose verification tool for IMRT plan based on DPM

Zhonghua fangshe yixue yu fanghu zazhi (2014)

Jinfeng Cai Hui Lin Yu-Mei Dai

Objective To build a Monte Carlo dose verification tool for IMRT Plan by implanting an irradiation source model into DPM code and to extend the ability of DPM to calculate any incident angles and irregular-inhomogeneous fields.Methods The virtual source and the energy spectrum unfolded from the accelerator measurement data were used,in combination with optimized intensity maps,to calculate the dose distribution of the irradiation irregular-inhomogeneous field.The irradiation source model of accelerator was substituted by a grid-based surface source.The contour and the intensity distribution of the surface source were optimized by IMRT.The dose calculation was realized by combining the position of the emitter with the fluence map from the IMRT plan.The weight of the emitter was decided by the grid intensity.The direction of the emitter was decided by the combination of the virtual source and the emitting position.The weighted fraction of the emitter was also combined with the flux grid intensity based on the particle transport model of DPM code.Results The accuracy of calculation was verified by comparing with the measured data.It was illustrated that the differences were acceptable (＜ 2％ inside the field,2-3 mm in the penumbra).The dose calculation of irregular field by DPM simulation was also compared with that of FSPB (Finite Size Pencil Beam).The passing rate of gamma analysis was 95.1％ for peripheral lung cancer.The regular field and the irregular rotational field were all within permissible range of error.The calculation time of regular fields were less than 2 h,and that of the test of peripheral lung cancer was 160 min.Conclusions The adapted DPM code with its simple irradiation source model is faster than that with classical Monte Carlo procedure.Its computational accuracy and speed satisfy the clinical requiremcnt,and it can be useful as a Monte Carlo dose verification tool for IMRT Plan.
