Northeast Power 500kV Iraq (Min) - Feng (Tun) system applications of TCSC technology systems
cPowerFeb. 2009Vo1.37No. 1 (Ser.No.200) 375t / h of biomass boiler model selection a. After a 75t / h of biomass boiler in the high temperature and pressure parameters and temperature high-pressure parameters of contrast, in addition to the boiler parameters, generator parameters and capacity, and capacity of the main auxiliary parameters, the main transformer capacity, power transformer capacity, Circulating Water Pump , changes in the larger area of cooling tower, the other the amount of system capacity and construction is essentially the same or micro changes. Point of view from the unit capacity,[link widoczny dla zalogowanych], high temperature and pressure in the boiler program than the program temperature high-pressure boilers to increase the generator capacity, single 3Mw, the capacity to improve 2O. b. Parameters of high temperature and pressure than the boiler temperature and high-pressure boiler parameters in the biomass power plant thermal efficiency of the plant above the 2. O5, reached 29.989,6; generation standard coal consumption rate 86.25g / (kW ・ h). C. High temperature and pressure parameters of biomass power boiler total investment of above parameters in temperature and high-pressure boilers,[link widoczny dla zalogowanych], but the unit project investment is low. d. Parameters of high temperature and pressure than the boiler temperature high-pressure boiler parameters above the grid electricity 3510X10kW ・ h, low-cost power generation units of 0.064 yuan / (kW ・ h). e. High temperature and pressure parameters of the biomass power plant boiler payback period than in the high-pressure boiler temperature and time parameters of the short 356 years,[link widoczny dla zalogowanych], that even if the high temperature and high pressure boiler parameters and invest in 3980 × 10 million, due to its higher power output, better economy, not only to advance recycling more investment funds, but also can make a total investment of the entire project ahead of schedule recovery. f. Temperature and time parameters in the biomass power station boiler pressure of capital and the net rate of only 0.12, meaning that owners of capital return on margin (on page 5) examples, such as Datong and Fangshan 500kV double-circuit series compensated transmission system, which ward along the line of the B group 150Mvar installed a high resistance, the great side of a line installed only in the Fangshan Group 1 150Mvar high resistance, the system has reliable operation for years. Comprehensive variety of electrical calculations, Yvonne high resistance to configure the system to adapt to the existing series compensation requirements and put into operation after the operation. 8 Conclusion Yvonne Northeast 500kV power grid system is typical of large-capacity, long range, extra high voltage AC transmission system, the first application of TCSC Yvonne system technology, to ensure that electricity sent Hulunbeier power and security of Northeast group AC-DC Power System Stability running at the same time, new lines can be avoided through the Daxinganling forests, to protect the precious original ecological environment. In the Northeast power grid technology using advanced TCSC is close to zero, economic bad, is not conducive to the development of biomass power generation project; high temperature and pressure parameters of power plant boiler capital and the net rate can reach 16.40%, the development of biomass power generation project a more favorable . g. Area per unit volume, the high temperature and high pressure boiler parameters than in the low-temperature high-pressure boiler parameters 0.245m/kw, land utilization is relatively high. 4 Conclusion By the same capacity of the boiler temperature and pressure parameters of biomass power station and the temperature high-pressure parameters of the biomass power plant technical and economic comparison, we can see that, although the high temperature and pressure parameters of a one-time total project investment than in the warm high-pressure parameters to be high, but the unit project investment power generation unit cost, total investment yield, and the net rate of grid electricity, power generation standard coal consumption rate, the whole plant thermal efficiency, technical and economic indicators are much better than in the high temperature and time parameters of the biomass power plant. So whether it is technically and economically show that the biomass-fueled boiler capacity should be selected as high temperature and pressure parameters. This is September 4, 2008 Department of Environmental Protection, the National Development and Reform Commission, the National Energy Board for Environment and Development (No. 2008382 \Projects should avoid duplication and to select a high parameter units,[link widoczny dla zalogowanych], in principle, construction scale of the project should be not less than 12Mw \technology gaps,[link widoczny dla zalogowanych], to further improve the overall technological level of the Northeast power grid and the degree of modernization, the Northeast power grid to the \Tuen feasibility study of TCSC [R].
