Yanshou Poverty-alleviation PV Grid Connection
High-cold photovoltaic grid-connection support in Yanshou, Heilongjiang — our team's participation.
Our engineering team participated in the grid-connection support of a poverty-alleviation photovoltaic project in Yanshou (Harbin), Heilongjiang, covering the PV step-up auxiliary distribution and grid-integration coordination.
Project background
The site is a high-cold region where low temperature and ice load are the dominant stresses on electrical equipment. PV collection needs a step-up and grid-connection path that stays reliable through winter.
Equipment & scope
- PV collection and step-up auxiliary distribution
- Grid-connection switching and protection coordination
- Winter-ready commissioning and inspection
What our team did
The team supported the collection-side distribution layout, protection setting for the PV interface and the staged grid-connection test, with attention to cold-weather commissioning practice.
Takeaway
High-cold PV needs equipment rated for the local temperature range and a commissioning plan that accounts for winter. Our solid-insulated switchgear is specified for -45 °C to +45 °C and altitude up to 4000 m.
