On April 21, the world's first 50 Mvar 4-pole non-salient pole distributed synchronous condenser independently developed by the company was officially shipped to the Huadian Power Kangping 300 MW wind power project site. The equipment has successfully passed all verifications and is fully ready for mass production and grid-connected application.

Currently, the installed capacity of new energy in China continues to grow. The large-scale grid integration of new power sources such as wind and photovoltaic brings a series of challenges, including reduced grid system inertia, insufficient voltage support, and weakened anti-disturbance capability.

The 50 Mvar 4-pole non-salient pole distributed synchronous condenser independently developed by Harbin Electric Machinery precisely targets the core requirements for the safe and stable operation of new energy power grids. It combines millisecond-level rapid dynamic response with long-term steady-state support capability, allowing it to intervene instantly under extreme conditions such as voltage dips and frequency fluctuations, effectively suppressing the risk of unit disconnection. It can be regarded as a "safety guardian" for new energy power systems, building a solid safety barrier for the integration of high-proportion new energy into the grid.

Compared with the traditional 50 Mvar 2-pole non-salient pole distributed synchronous condenser, this model achieves a comprehensive performance leap through independent innovation in core technologies, overcoming many common industry challenges.

This model offers stronger grid support capability, with a significantly increased short-circuit ratio, greatly strengthening the system strength at the grid connection point and effectively enhancing voltage support capability, making new energy power stations more resilient and stable during grid fluctuations. Its rotational inertia is increased by more than 500%, substantially enhancing the grid's dynamic resilience, quickly damping power oscillations, fundamentally reducing the risk of new energy unit disconnection, and ensuring continuous and reliable power generation.

This model operates more energy-efficiently and smoothly, with significantly improved unit operating noise, which optimizes the working conditions for site personnel and strengthens regional ecological friendliness, deeply aligning with the green and low-carbon development concept. Its carbon brush maintenance cycle is extended by more than half a year, effectively streamlining maintenance work and reducing repair costs, comprehensively improving the economic efficiency of equipment operation.

This model has higher safety and reliability. Its stator lead-out wires adopt Harbin Electric's proprietary patented structure, effectively increasing the corona inception voltage, fundamentally suppressing corona corrosion from the structural source, and significantly improving insulation reliability and equipment operational stability. This model is the only synchronous condenser in China that adopts high-performance, low-loss tilting pad bearings, offering superior load capacity and operational stability, ensuring long-term stable operation of the unit.

The breakthrough of the world's first 50 Mvar 4-pole non-salient pole distributed synchronous condenser not only enriches the high-end synchronous condenser product portfolio of Harbin Electric Machinery but also provides a completely new technical solution for the safe and stable operation of China's new energy power grids.
