Preface 1.1 esson For Construction 1.1.1 The Present Situation and Problems of Ningbo's Power Distribution Network Niugbo is the major provincial city of Zhejiijg Province and one of the key open cities of China that individually accounted in the economic planning. Niabo' s power distribution network has a history of more than 30 years, with a considerable scale. Now Ningbo city hls 2 220KV transformer substations (total eapacity 390,000 KVA) , 12 110KV transformer substations (total capacity 724, 600 KVA) and 25 35KV transformer substations (total capaeity 251,200 KVAJ, 3609 1OKV transformers (total capacity 687,700 KVA), a total 1624. 6 km length of 1o RV circuits (see Table-1. 1. 1) . It has a total 2044600 [VA of transformation capacity. The capacity for power plants' generators is 1650000 KW( Zenghai 1060000 kw,Beilun 600000 kw).In 1990 the city proper has a power supply of 230700 K,yearly power supply 1.356 billion kwh. The problems of Ninbo' s power network include: (1) Geographically divided by Tong River, Fonghua River and Yuyao River, the linkages between 220KV and 110KV electric source points are rather weak. The dependability of power networks is poor; (2) The city proper of Niabo now hag Zengkai Power Plant (capacity 1.05 million kw), and Beilu1n Harbour Power Plant  II V \ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Zhe#4i W e pI.
