摘　　要：基于电力行业标准《交流电气装置的接地》推荐的水平接地网接地电阻的计算公式，提出了计算复合接地网接地电阻的简化公式。用该公式计算的结果与用矩量法、边界元法计算结果进行了比较，比较结果表明简化公式可供工程使用。On the basis of calculation formulae for ground- ing resistance in horizontal grounding network, which is rec- ommended in the industrial standard of electric power' Grounding of AC Electrical Devices', in this paper the simpli- fied formulae for the calculation of grounding resistance in compound grounding network are put forward. Calculation results by these formulae are compared with that by other methods, e. g., the boundary element method etc., the com- parison results show that the simplified formulae can be used in engineering calculation.
