一种基于改进斜率调节的DSTATCOM群无功电压协调控制方法
摘要：
本发明公开一种基于斜率调节的DSTATCOM群无功电压协调控制方法，用于解决同一区域内多个DSTATCOM的无功互补问题，包括以下步骤：建立计及网架参数条件下无功电压和斜率调节下的DSTATCOM输出无功电流之间的关系；接着根据装置的最大无功容量整定各个DSTATCOM的调节斜率，合理分配各个装置的无功输出；最后在基准电压基础上加入比例增益作为负反馈，构成DSTATCOM新的电压参考值，建立基于斜率调节的DSTATCOM群协调控制方法。使其在无需通信的情况下，多个DSTATCOM在斜率调节下进行协调控制，实现各个无功补偿装置的无功输出分配合理，在实现设备的优化运行的同时确保电网的安全稳定运行。
摘要（英）：

The invention discloses a coordination control method of reactive voltage of a DSTATCOM group based on slope adjustment. The method is used for achieving reactive complementation of a plurality of DSTATCOMs in the same area. The method comprises the following steps of establishing a relation between the reactive voltage under a net rack parameter condition and DSTATCOM output reactive current under the slope adjustment, setting an adjustment slope of each DSTATCOM according to the maximum reactive capacity of devices, reasonably distributing reactive output of each device, adding a proportional gain as negative feedback based on reference voltage, forming a new voltage reference value of each DSTATCOM, and establishing the coordination control method of the DSTATCOM group based on the slope adjustment. According to the method, the DSTATCOMs are subjected to coordination control based on the slope adjustment under no communication; reasonable distribution of the reactive output of each reactive compensating device is achieved; optimized operation of equipment is achieved; and safe and stable operation of a grid is ensured.
