摘要
随着钢铁企业自备电厂发电率的提高,为发电机孤网和企业电网系统进入最小系统模式的运作方式提供了有利条件。而根据当前企业电网系统的运行状况可提出最小运行方式的系统数学模型,通过辨别优先级来迅速求解各线路的运行(负荷)状态,切除对应负荷,改变运行方式使发电机进入孤网运行,企业电网系统进入最小方式运行模式。在通过暂态仿真计算后,证明其具有可行性。
Increasing power generation of steel enterprises＇ self-own power plants has provided favorable condition for isolated grid of generators and enterprises＇ power plants to enter the minimum system operation mode. According to the operating conditions of current power grid systems of steel enterprises, the system mathematic model of minimum operation model can be put forward. By identifying the priority to quickly solve the operation （load） state of each line, cut off corresponding load, change operating mode to let the generator enter isolated grid and the steel plant grids enter the minimum operating mode. The feasibility has been proved through transient simulation.
