The planned Three-Gorge Hydro Project (TGHP) is located in The Central Power Network of China (CPNC). CPNC and The East Power Network oE China are planned to achieve the interconnection through two bi-poie DC links and three circuits of 500kV AC power ties for transfering about 6000-7000MW of electric power from the west to-the east. In order to enhance the transmission capability of the ties, the DC modulation principle, and its results, and its function in the TGHP AC-DC parallel transmission system are described in this paper. The minimal time control theory is used for DC modulation and the sub-optimum control modes are suggested, i.e. phase angle shif (A) and frequency shif (f) modulating modes. During fault condition either in EHVAC or HVDC, 0 or f is used as a control signal to change the transfer power of HVDC immediately, thus the whole interconnected AC-DC system will reach a stable state within a minimal time period. As the digital study indicated that the power unbalance between the sending and receiving ends caused by either the severe fault on the EHV tie-line or the permanent fault on two poles of HVDC line can be decreased rapidly, and the power oscillation can also be damped effectively. Using above stated modulation method, the transfer capability of TGHP can be increased by 10%. Instead of DC modulation, the strategy of generator triping 4x500MW at TGHP will be necessary to maintain similar stability level.

Using the experimental data, the relations among the regional scales, mapping scales, visual effects of the maps, data precision and data loads of the regional ecological environmental system security assessment in midscale (scale of 1∶100 000) were systematically studied and the digital study environmental framework of the assessment on regional scale of the ecological environmental system security were gained. The midscale GIS raster assessment unit size of the regional ecological environmental system security that the 25 m×25 m raster GRID unit was set up. The result of this paper can be regarded the technology methodology and the theory basis as establishing midscale as well as any other scales of GIS raster sizes of the regional ecological security assessment units.

在研究实验数据的基础上,对中尺度(1∶100000比例尺)区域生态环境系统安全评价的区域尺度、制图尺度、成图视觉效果、数据精度、数据量负荷之间的辨证关系进行了系统的研究,建立了中尺度区域生态安全评价的基本格网分析评价单元———即25m×25m的GRID格网单元。研究成果建立起了区域生态安全评价研究基本格网评价单元确定的方法论。
