哪位大侠能帮我翻译成英文，毕业论文要用，急啊~~多谢各位了,不要机器翻译啊

绝对我自己的翻译，我就读墨尔本大学，因为水平是可信的。。。

3 discuss and Suggestions
Through the comparative analysis, we can see different initial conditions, and the calculation method of different, its short-circuit current calculation results will have obvious difference. Should say, based on the trend of short-circuit current calculation results are the most accurate. As long as all the generator all run, system based on the wiring, tide of short-circuit current calculation, which can reflect the equivalent impedance is the largest system in operation of the impedance values. Besides all the common parameter calculation method, affect the fault of equivalent impedance values are the major factors: the pressure is changed, the parallel compensation, line than charging capacitance, etc, which are the transformer and parallel compensation effect is relatively small, while charging circuit. Capacitance
But the problem is: (1) based on the trend of short-circuit current calculation, the whole system of short-circuit fault before all voltage doesn't guarantee is the maximum operating voltage system may be. In the tide of generator power factor can not actually reflect the maximum load. Generators, And this is the impact equivalent voltage source fault port calculation of main factors. (2) maximum short-circuit current calculation, and all are running for generator power system reliability, the system of redundancy, generators, always have a spare, with the tide, the calculation is a huge challenge. Therefore, it is advisable to take the following method for grid three-phase short-circuit current calculation.
In the whole wiring tide files based on calculation of tide, should include the whole operation units, generator with zero output machine group said.
2 this way of calculating under short-circuit current, more specifically, is calculated under the way, each node of the system, the equivalent impedance equivalent impedance is system of each node minimum equivalent impedance reality.
3 each node may according to the system of the highest level of operating voltage, each node of the biggest short-circuit current. According to the law, the equivalent electric pressure source short-circuit current equivalent impedance voltage divided for node.
4 epilogue:
Short circuit calculation and analysis is power system meter.with is an important content of a calculation, the calculation results of the power system security and stability is of great significance to the economic operation. Through the analysis of some commonly-used calculation method, we can find that the classic method of calculating square short-circuit current calculation results of small, may give system buried unsafe. Based on the method of IEC short-circuit current trends are small, but the result of the deviation in different areas varied, also does not necessarily reflect the maximum short-circuit flow level. If a thought, the biggest short-circuit current calculation node for calculating the minimum equivalent impedance, the system is easy to calculating the minimum equivalent impedance, and can meet the practical system. On this basis, the largest possible according to each node, electric pressure to run the node's biggest short-circuit current level, should be the most can reflect the largest possible system short-circuit current level of feasible method.
