基于关联特性矩阵的电网安全控制系统设计

Design of Grid Security Control System Based on Correlation Characteristic Matrix

在当前的电网安全控制系统中,控制因素为发电功率、负荷、交流母线电压。但由于控制过程未考虑三者的关联性,在只能以其中一个因素为控制目标时的控制效果较差。为此,设计一种基于关联特性矩阵的电网安全控制系统。首先,设计电网运行因素控制软件,并在软件数据库内构造关联特性矩阵,明确电网安全控制系统中发电功率、负荷、交流母线电压的关联关系,以实现多因素协同控制。然后,设计系统功能部分控制与预警模块,将关联特性矩阵与设计的系统功能模块相结合。最后,对电压、发电功率、负荷进行协同控制,以实现电网安全控制系统设计。试验结果表明,所设计的系统能够将电网的发电功率、负荷及交流母线电压控制在设定范围内。所设计的系统具有较高的可靠性,可提升电力系统的安全性和稳定性。

In the current grid security control system,the control factors are generation power,load and alternating current bus voltage.However,the control process does not consider the correlation of the three,it is in poor control effect when only one of them can be used as the control target.For this reason,a grid security control system based on correlation characteristic matrix is designed.Firstly,the grid operation factor control software is designed and the correlation characteristic matrix is constructed in the software database to clarify the correlation relationship among generation power,load and alternating current bus voltage in the grid security control system,so as to realize the multifactor synergistic control.Then,the control and warning module of the system function part is designed and the correlation characteristic matrix is combined with the designed system function module.Finally,the voltage,generating power and load are synergistically controlled to realize the design of the grid security control system.The experimental results show that the designed system can control the generation power,load and alternating current bus voltage of the grid within the set range.The designed system has high reliability and can improve the security and stability of the power system.
