Global Solar and Wind Power Industry

Solar power generation is an important direction for new energy development. Taking the photovoltaic design scheme of 40 building or factory roofs with a total capacity of about 1 MWp as an example, the components are connected to the grid after converging, inverting and distribution. The insulation monitoring and fault location configuration should correspond to the actual branch, grid-connected structure and fire protection design requirements.

New energy: wind power, solar energy

Wind power generation and pitch systems use ungrounded power supply circuits, and online insulation monitoring can be configured according to the design. The insulation status of the windings after long-term shutdown also needs attention, and the re-operation should be arranged in conjunction with operation monitoring, shutdown inspection and equipment maintenance requirements.

Photovoltaic modules, combiner boxes and inverters form an interconnected electrical path. Insulation degradation may affect operation, and the monitoring configuration should match the system structure and protection requirements.

Continuously observe changes in residual current and insulation status to provide information for maintenance personnel to identify abnormalities, arrange inspections and track operating trends.
