In August 2022, historic high temperatures will appear in many parts of China. Due to the continuous high temperature in Sichuan Province, power consumption will increase greatly, resulting in insufficient power supply in some areas. The government announced that in order to ensure the people's livelihood, all industrial power users will be shut down for six days. Affected by this, all kinds of factories in Sichuan were shut down, which had a significant impact. Internationally, global climate change and international crisis events have heated up the "energy topic" again, and pushed the global development of new energy into a fast lane.

In China, based on the commitment of "double carbon", the new power system with new energy as the main body is accelerating the reform, and the installed capacity and power generation of new energy represented by wind power and photovoltaic will gradually increase. It is estimated that by 2030, the installed capacity of wind power, solar power and other new energy power generation will exceed that of coal power and become the largest power source in China. By 2060, the proportion of new energy power generation is expected to exceed 50%. The rapid expansion of new energy brings both opportunities and challenges. The industry urgently needs a series of new technologies and products based on the characteristics of new energy.

From the power supply side, with the increase of the penetration rate of new energy installations represented by wind power, the "reverse load" characteristics of low wind power in the day and high wind power at night will greatly increase the stability risk of the power grid. On the grid side, more and more distribution networks connected with distributed new energy also greatly test the elasticity of distribution networks. From the power demand side, the peak valley difference of power grid load in China is increasing year by year. With the development of the city and the deepening of the degree of electrification, the replacement of electric energy in the industrial field and the increase of the number of electric vehicles in the transportation field will break the original relatively stable law of electric energy demand dominated by industrial and residential electricity, which will further amplify the impact of new energy access on the stability of the power system.

It can be seen that the challenge brought by new energy is a systematic challenge that runs through the whole process of source network load storage, and the related problems are interlinked and mutually restrained. Therefore, in order to meet the challenges, it is necessary to make full use of digital technology, make a comprehensive layout from the perspective of covering the whole life cycle, and go deep into each link to break through the barriers one by one, and finally achieve linkage.

The reliability requirements of the new power system for the new energy power generation system are far higher than before, which requires that the power generation project should take safety and stability as the most important task in the operation. On the one hand, the large-scale wind turbine and the special industry attribute of high offshore wind power construction cost put forward higher requirements for high performance and reliability of electrical products; On the other hand, because large scenery bases are often built in high altitude, sea, desert and other areas, and in harsh environments, coupled with the environmental sensitivity of electrical equipment, the performance and durability of power generation components are the key to supporting the source power of the new energy industry. On this premise, in order to solve the security challenges of the production side of the new energy industry, Zhongcheng Excellence provides different product portfolios and solutions for wind power generation scenarios.

Continuing the consistent product quality standards, Shenzhen Zhongcheng Excellence provides safe, durable, high-performance and cost-effective components and parts to the new energy industry through innovative and agile research and development, effectively ensuring the reliability of the new energy power generation system. In fact, Zhongcheng Zhuoyue has already laid out offshore wind power, designed and developed wind equipment power supply, dedicated pitch servo driver and other products specifically for offshore wind power according to different offshore and onshore wind power environments.

The next few years will be a critical period for the innovation and reform of offshore wind power technology in China. The application of new large capacity units, the investment of specialized construction ships and equipment, and the popularization of digital technology will drive the reduction of life-cycle costs. It is estimated that in the next three years, China's offshore wind power is expected to achieve parity online, and offshore wind power will be an important stage for future wind power development. Zhongcheng Excellence's pitch drive and pitch motor developed for offshore wind power have built a stable "cornerstone" for safe and reliable operation in various power generation scenarios through the severe tests of salt fog, vibration, high and low temperature in harsh environments with strong durability.

Faced with special application scenarios of offshore wind power: high humidity, high salt fog, ultraviolet radiation, alternating dry and wet conditions formed in the splash zone and other operating environments, Zhongcheng Excellence launched a special pitch driver for offshore wind power, which not only meets the requirements in terms of performance, but also fully complies with IP grade full protection in the cabinet, and the shell is made of 316 stainless steel. The material itself can resist corrosion, and the service time can reach 3000-5000H, The salt spray test standard can reach above 1440H, which is far beyond the 720H required by customers. The 75A dedicated offshore servo driver is currently the servo driver with the highest power density in the industry. Compared with other similar products, although the current output is the same, the volume is much smaller. This design alone will reduce the space of the client unit and save costs.

Sustainability is not only an enterprise proposition, but also an industry proposition. Shenzhen Zhongcheng Excellence contributes innovation vitality to the industry by cooperating with customers through an open cooperation model. As the core technology of new energy in the field of wind power development, Zhongcheng Excellence, under the guidance of safe, efficient and green standards, will also work with new energy industry partners to meet challenges and overcome all difficulties through reliable and excellent product quality. It is believed that in the future, we will witness the shift acceleration of the new energy industry on a sustainable development path, and share the high-quality green development achievements of the industry.
