The Communication Mode of The Master Station Based on COA Algorithm to Optimize PDU and TPDU Parameters of Large Data Transmission

Aiming at the important parameters of protocol data unit (PDU) and transport protocol data unit (TPDU) in the process of fault and big data transmission, this paper proposes a communication mode of the main substation with guaranteed confidence based on the optimization technique of coati optimization algorithm (COA). Based on network architecture of the guarantee system and its PDU and TPDU parameters, this paper establishes a maximum flow communication model considering the constraints of recording communication duration and instantaneous flow, and COA algorithm is introduced to optimize the parameters, so as to realize the optimal bandwidth configuration under this background. The test of multi-category substation communication services is carried out and the stress test of communication network under extreme conditions is considered. The proposed method can effectively improve the information transmission capability and reliability of the substation.
