摘　　要：针对韶关电网的现状和特点,利用暂态风险评估方法和模型对韶关电网进行安全风险评估。采用BPA数字仿真计算程序分析了韶关电网的暂态电压稳定性,以2009年韶关电网220kV主网的3种典型运行方式为评估对象,通过MATLAB编程,对单一故障和严重故障时电网的暂态风险进行评估,并对如何降低韶关电网的运行风险提出了相关的建议。Aiming at the features of the power networks in Shaoguan district,transient risk assessment and mode are used to assess the security risk.With the digital simulation program BPA,the transient voltage stability of Shaoguan power grid is analyzed.Three typical operation modes have been assessed for the main 220 kV power supply network in Shaoguan district in 2009,through MATLAB programming transient risks of single faults and severity faults for network are assessed,and the relevant recommendations on reducing the risks of Shaoguan power grid are proposed.
