Vietnam is located in an area with a fairly high ground flash density [3], with ground flash density of 1.4 -14.9 times/km 2 .year, so the number ABSTRACTWind power is one of the growing renewable energy sources to meet the rapidly increasing demand for loads, in the context that traditional energy sources are increasingly limited and discouraged for development. However, wind power also has many disadvantages, one of which is frequently lightning strikes to the wind turbine blades, causing economic damage and disrupting power supply. There are many factors affecting to transient overvoltage when lightning strike to in wind power farms that have not been studied, in Vietnam, few published works. This paper analyzes some factors affecting lightning overvoltage in wind farm such as parameters of lightning current, grounding system of turbine, application of lightning surge arrester (LSA) installation solution, identifying the over voltages at the low-voltage and high-voltage side of the transformer. The results show that applying this solution can reduce the overvoltage value caused by lightning on the low voltage side by 60 times and the medium voltage side by 3 times. From these analysis results will be the basis for choosing effective lightning protection solutions for wind turbines. Research results are carried out using The Electromagnetic Transient Program Alternative Transient Program (EMTP/ATP).

“…As can be observed from Fig. 1 [34,35], the surge arresters are a significant part of the lightning protection strategy for the wind turbines electrical system. It can be seen from this figure that the surge arresters are connected to the grounding conductor and the tower base grounding network represented by R g .…”

a b s t r a c tThis paper proposes a modelling and simulation process for assessing the energy absorption capability of metal oxide varistor (MOV) surge arresters used for lightning protection of wind turbines electrical systems situated in wind farms, when exposed to multiple lightning strokes. A section of an existing wind farm, suitable for lightning transient overvoltage analysis is implemented in the Electromagnetic transients programme-Alternative transients programme (EMTP-ATP) environment and modelled as a test system for analysing the energy absorbed by the medium voltage surge arresters when multiple lightning strokes are terminated on one of the blade of the wind turbines. Two well-established sets of multiple lightning current parameters are employed in the EMTP-ATP simulations; the natural downward negative multiple lightning strokes recommended by CIGRE TB 549 (2013) and the downward positive multiple lightning strokes recommended by IEC 61400-24-2010 for lightning protection level one (LPL1). The results show that the subsequent stroke causes the surge arresters to absorbed less than ten percent additional energy compared to that of the first stroke. This comparative analysis could be found beneficial when designing lightning overvoltage protection system and for selecting the most cost effective and optimal energy absorption capabilities of the surge arresters for the intended wind farms.
