LDAPF adopts a modular design.Each module unit operates independently and intelligently allocates compensation capacity; any module is automatically returned after failure, and the remaining modules are automatically allocated compensation capacity.According to the N + 1 redundancy theory, each level of redundancy of the equipment can ensure reliability. Improve an order of magnitude; the modular structure is particularly suitable for load occasions with higher reliability requirements; at the same time, it can be used in conjunction with third-party passive compensation products, which can comprehensively consider compensation accuracy and cost, save investment, and achieve cost-effective power quality Governance system.
