In recent years, the power quality management system market gained rapid development driven by various parties, especially in the aspects of filtering device and reactive-load compensation equipments, and the compound annual growth rate was more than 16%. In 2011, the scale of China’s power quality management market reached CNY 8 billion. It is estimated that this market will keep the annual growth rate of 12% to 20% during the “Twelfth Five-Year” period, and the market scale will exceed CNY 12 billion and CNY 19 billion in 2015 and 2017 respectively.
China is still in the primary stage in the power quality product field, and many early built large-scale enterprises have not completed the automation transformation, therefore, the demand for power quality management devices accounts for about 70% of the total demand for power quality products. Monitoring device & software and service account for about 15% of the overall market respectively, and the proportion accounted by monitoring device is slightly higher.
Power quality product manufacturing industry is in the initial stage of emerging industry, and becomes a key research and investment filed for the enterprises at home and abroad, and also, this filed is supported by national policies. In the macro context of energy saving and emission reduction, the market space was enlarged sharply, which drives many enterprises, including many listed enterprises to join the production of power quality products; this situation gradually intensifies the market competition.
Among the domestic enterprises, Rongxin Power Electronic Co., Ltd and C-EPRI Science & Technology Co., Ltd occupy the leading position in the fields of power grid reactive power compensation and harmonic management; the products of Sieyuan Electric Co., Ltd also occupy certain market share in this field.
There are more than 1,000 enterprises that engaged in the fields of public power quality improvement, harmonic management devices and reactive power compensation devices production, however, very few enterprises can research and produce dynamic reactive power compensation devices and active harmonic management devices at the same time. At present, the key enterprises in public power quality improvement field are: Sinpower Electric Co., Ltd, Shandong University Hoteam Science & Technology Co., Ltd, Hubei Surpass Sun Electric Co., Ltd and Shenzhen Sinexcel Electric Co., Ltd, etc.
