“…There are three different types of this method. These are direct current deicing method, short circuit current deicing method, over current deicing method (Heyun et al, 2001; Liu et al, 2012; Wang, 2010). Its use in this method is limited.…”

“…Generally, the three-phase short circuit method is used more (Li et al, 2006). In the direct current ice melting method, heat is generated by using direct current through the high voltage line, this heat is used to melt the ice (Liu et al, 2012). This method needs a large power supply.…”

The world’s energy demand is increasing. Wind energy plays an important role in meeting this demand. Investments in wind energy have been increasing in recent years. It can be said that the source of wind energy will be unlimited since there will be wind as long as there is sun. Most governments meet a large energy need by generating electricity from wind. At the end of 2019, the total amount of electricity generated from wind was 650 GW. Wind energy capacity is increasing with offshore wind pairs. Offshore wind turbines are a new field and research studies are ongoing. Wind turbines have the capacity to be installed anywhere in the world, and each government will have its own energy source. There is a problem of icing in wind power plants installed in cold climates. With this problem, efficiency in wind turbines decreases. Many methods have been found and developed in studies on icing problems. In this article, wind turbines were investigated, states’ perspectives on wind energy, developments and investments in wind energy, and the problem of icing were examined. Many articles in the literature have been reviewed and a solution to the icing problem of wind turbine blades has been sought.

“…The SVG and the transformer realize dynamic reactive power compensation. The SVG can provide fast and flexible dynamic reactive power for the power grid, support the grid voltage especially when ice-melting, and improve the stability and power quality of the power system [13][14][15]. In the structure shown in Figure 1, the leakage reactance of the transformer is used as a connection reactance to replace the special reactor connected to the SVG and the grid, reducing the land occupation and cost of the SVG.…”

As a result of the high efficiency of ice-melting and the small power supply capacity, DC ice-melting devices are widely used in relation to transmission lines in the power grid. However, it needs to consume reactive power when ice-melting, and voltage fluctuation of the substation may be caused when the demand for reactive power is large. It also generates a large number of 5th and 7th harmonics when ice-melting. In this paper, combined with the demand for ice-melting for transmission lines and the dynamic reactive power of substations, a low-harmonic DC ice-melting device capable of simultaneous reactive power compensation is studied. The function of ice-melting and reactive power compensation can be operated simultaneously and the rectifier's main harmonics can be eliminated. The simulation and experimental research on the device was carried out in the 500 kV Chuanshan substation. The actual ice melting was carried out on the 500 kV Chuansu I line and took only 68 min to melt the ice. The 500 kV bus voltage had no negative deviation, and the positive deviation decreased from +3.09% to +1.57% within 24 h of testing. The results prove the feasibility of the proposed DC ice-melting device in this paper.
