Systematic Solutions

HV DC power transmission can be applied to the followings: long-distance high-capacity transmission of electric energy, asynchronous grid connection of power system, long-distance power transmission through submarine cables, high-capacity grid connection of new energy, power supply to weak AC system or passive system and building of urban DC distribution network etc.

China XD Group Co., Ltd. is dedicated to creating full-industry-chain products covering development of wind power plants, design of power plants, supply chain services, project construction, commissioning and O&M and financial solutions by bringing the resource advantages of central enterprises into full play and integrating industrial resources such as suppliers...

In the process of developing towards deep/open sea, the previous AC transmission schemes of offshore wind-power development cannot meet relevant requirements under limitations from transmission distance. On the contrary, the flexible DC access scheme is the optimal technical scheme for grid connection of open-sea wind power field recognized on the international community currently.

Based on advanced power electronics, microelectronics and control theories, China XD Group Co., Ltd. studies on schemes of systems such as microgrid and comprehensive energy, forming serialized products such as microgrid and comprehensive energy control and protection system after years of technical R&D. China XD Group Co., Ltd. is now capable of providing users with solutions for microgrid and comprehensive energy system.

With regard to voltage flicker and fluctuation, three-phase imbalance and harmonic wave of the power grid, the solutions based on Passive Filter (FC), Static Var Compensator (SVC), Static Var Generator (SVG), Active Power Filter (APF) and Dynamic Voltage Restorer (DVR) are used. In this way, the reactive power can be regulated to support grid voltage, to eliminate the harmonic pollution and to compensate the unbalanced current of the load, realizing comprehensive quality control of electric energy.
