Distributed Phase-Shifting Machine
With the implementation of the new GB 38755-2019 Guidelines for Security and Stability of Power Systems, requirements for short-circuit capacity and inertial support at new-energy stations have risen sharply. Distributed synchronous condensers are thus set to become standard equipment at such stations. High-capacity synchronous condensers offer outstanding reactive-power compensation; their sub-transient characteristics keep the internal voltage practically constant during faults, allowing them to absorb or inject large amounts of reactive power instantaneously and thereby safeguard grid operation. In particular, as the country vigorously expands its new-energy power sector, the deployment of distributed synchronous condensers can effectively counteract current surges, frequency deviations, voltage fluctuations and flicker—mitigating the inherent volatility and intermittency of renewable-energy sources.

Flywheel Energy Storage System
Flywheel energy storage constitutes a physical energy storage method, harnessing the kinetic energy inherent in a rotating body to store and release electrical energy. This conversion between kinetic and electrical energy is achieved via an electric motor/generator coaxially mounted with the flywheel assembly. When operating as a motor, the drive unit accelerates the flywheel rotor, converting input electrical energy into stored kinetic energy. When operating as a generator, the drive unit decelerates the flywheel rotor, converting stored kinetic energy back into electrical energy for output. The acceleration and deceleration of the drive unit are controlled by a dedicated control unit.

ORC Waste Heat Power Generation System
·The Organic Rankine Cycle (ORC) power generation process involves extracting heat from waste heat sources (such as hot water, flue gas, or steam) via heat exchangers. This heat drives an expander to perform work, thereby powering a generator to produce electricity. ·The 125kW, 315kW, and 500kW ORC waste heat power generation systems developed by Xiangdian, featuring fully independent intellectual property rights, have completed industrialised operational trials and are now generating electricity stably. Their thermal-to-electric conversion efficiency reaches internationally leading levels, filling a technological gap in China's industrial waste heat recovery sector.

In modern industry, process operations frequently involve the direct discharge of substantial quantities of low-grade steam, or within cascading energy utilisation systems, the pressure energy of large volumes of high-grade steam is directly reduced, resulting in the wastage of residual pressure. High-speed steam turbine equipment, designed and manufactured using German turbine technology, can harness the residual heat and pressure in such scenarios, thereby enabling enterprises to conserve energy and reduce consumption.
