摘要:
对于阀厅全模型电场强度数值模拟,电位加载方式不同时,阀厅内部金具上的电场分布是不同的,因此有必要对典型相序时的电位、电场分布进行仿真分析。笔者根据阀厅设备电位波形特点,提出瞬时电位加载法进行电场计算,能够真实模拟阀厅内部电位各种频率分量的作用。相对于两重阀而言,四重阀阀塔周围金具连接结构复杂,电场计算难度较大。基于文中提出的方法,依据昭通±500 kV换流站阀厅四重阀真实模型,建立有限元仿真模型,通过计算得到了阀厅内部金具表面电场强度的最大值,为阀厅内部金具的电晕控制提供了依据。
Abstract:
When the numerical simulation of the whole model of valve hall being done, if the known potential applied in different ways, the electric field distribution on surface of fittings within valve hall is also different. So potential and electric field simulation under the typical phase sequence is much needed. According to the waveforms of potentials appeared on the equipment in the valve hall, the transient potential application method is presented to calculate the electric field, which can really simulate the application of the potentials in valve hall with various frequency components. Compared to double-pulsed valve, the connection configuration of fittings in quadruple valve is relative complicated, and the difficulty of electric field calculation is also relatively high. Taking the real model in Zhaotong ±500 kV HVDC convertor station as example, the finite element simulation model is built up, the maximum field strength on surface of fittings is obtained which provide a reference for corona control in valve hall.
