The invention relates to the field of electrical power system network source coordination, in particular to a network source coordination management system and method based on a J2EE platform. According to the system, a first-area network and a second-area network are connected with a third-area network separately; a forward and reverse isolating device is connected between the first-area network and the third-area network, and a forward and reverse isolating device is also connected between the third-area network and the second-area network; the third-area network is connected with a database server, a file storage server and two application servers separately; the database server and the file storage server are connected with an optical fiber storage network separately; the third-area network is connected with a user through a wireless network router. Therefore, accurate data reserve is supplied to power grid frequency and voltage control, safe and stable operation of an electrical power system is guaranteed, the economic losses in the frequency and voltage controlling process are greatly reduced, and then the great economic benefit is generated.
