摘要
本文利用MATLAB Simulink中的免费开源软件Power System Analysis Toolbox (PSAT)和专为发电、配电和工业电力系统的仿真、运行和自动化而设计的Electrical Transient and Analysis Program (ETAP)软件，对孟加拉国国家电网现有的达卡电网圈进行了负荷流仿真。模拟的所有数据均来自孟加拉国电网公司(PGCB)，采用Newton Raphson方法进行潮流分析，并将模拟结果与PGCB基准案例数据进行比较。我们正在考虑模拟的网络有71个母线(400、230和132千伏)，135条互连线，32个发电机，47个负载，只有4个分流电容器。关于负荷中心的最大需求，该系统连接的总负荷为5,525兆瓦，2018年9月的平均电网发电量为10,919.57兆瓦，尽管总发电量中只有5988兆瓦被纳入达卡电网圈。
Load Flow Analysis of Dhaka Grid Using PSAT and ETAP and Performance Comparison to PGCB Data
This paper deals with a load flow simulation of existing Dhaka Grid Circle of Bangladesh National Grid by using Power System Analysis Toolbox (PSAT) which is a free and open source software of MATLAB Simulink and Electrical Transient and Analysis Program (ETAP) software designed for simulation, operation, and automation of generation, distribution, and industrial power systems. All the data used to simulate were collected from Power Grid Company of Bangladesh (PGCB) and Load flow analysis was carried out using Newton Raphson method and simulated results were compared with PGCB Base Case Data. The network we are considering to simulate has 71 buses (400, 230 and 132 kV), 135 interconnecting lines, 32 generators, 47 loads and only 4 shunt capacitors as per the Dhaka grid circle system. Regarding the maximum demand of the load centers, total 5,525 MW load is connected in this system and the average grid generation in September, 2018 was 10,919.57 MW, though only 5988 MW of the total generation is enlisted in the Dhaka grid circle.
