The paper introduces the actual operating circumstance of Fushun--Yingkou oil product pipeline,and analyzes and discusses the maximum delivery capacity and optimally economic throughput of this pipeline.

Wrth development of high production and high productivity mechanized faces in the recent years investigation has been made in calculation of main parameters of AFC, such as, transport capacity, cross-section of chute for coal passage, power of motors, strength of chains etc.

Analysis and research to improve grid transmission capacity by reforming excitation system;

Improving cross-regional transmission capacity of large interconnected grids;

To deal with the increasing demand for transmission capacity,the East China Power Grid effectively carried out the static and dynamic capacity-increasing work.

Study of transmission capability of the Anhui Power Grid at the last stage of "The 11th five-year plan";

Routine shunt reactor fixed on the EHV transmission system can not guarantee the transmission capability and steady state voltage of system under different operation modes.

To satisfy the demand of high capacity and long distance power transmission and power load increasing rapidly, it is necessary to adopt some technical measures for improving transmission ability of power network.

This paper mainly introduced the significance of study on improving the transmission ability of 500KV power network in SGCC.
