Abstract

There are two synchronous compensators (SCs) with the capacity of 300 MW in Hunan network. At present, a SC is normally controlled within ± 50 Mvar and the other one operates in spare. There are rarely participates in regional voltage control. However, the problem of high voltage occurs frequently in the central Hunan during low load periods. Under the voltage safety premise of the most serious three phase fault, the SC participating in the regional voltage control method will improve the grid operating characteristics, and improve the safety and economics of the grid operation. In addition, this paper analyzes the relationship between the SC output reactive power and the number of thermal powers must on and its rotation reserve. By replacing the thermal power units and its rotation reserve which are the requirements for system stable operation, the SC in leading-phase operation can therefore improve the operation flexibility of power grid, increase the maximum transmission power of DC and the power supply capacity of Hunan power grid.

同步补偿器进相运行对湖南电网暂态和稳态的影响

湖南电网有两个容量为300mw的同步补偿器。目前，一个SC通常控制在±50mvar，另一个在备用状态下运行。很少有人参与区域电压控制。然而，湘中地区低负荷期高电压问题频繁发生。在三相故障最严重的电压安全前提下，电网参与区域电压控制方式将改善电网运行特性，提高电网运行的安全性和经济性。此外，本文还分析了电网输出无功功率与必须接通的火电数量及其旋转储备之间的关系。通过替代系统稳定运行所要求的火电机组及其旋转备用，使电网的运行灵活性得到提高，提高了直流的最大输送功率，提高了湖南电网的供电能力。
