The invention provides an implementation system and method for delay information during intelligent substation process level network switching. Delay of relay protection network data traffic inside network nodes is informed through the time stamp position and hardware timestamp determining technology, and therefore network transmission delay is determined. According to the implementation system and method, the delay inside the network nodes is measured, and the method is high in operating rate, high in precision, easy to implement and capable of accurately and rapidly measuring the delay of the network nodes, so that the problem that the delay of the relay protection service network data is not known is solved, supports are provided for relay protection network sampling and tripping, and the implementation system and method have practical engineering application value.

The invention discloses a seamless communication method for a substation and a dispatching master station. The method comprises the following steps: an IEC61850 proxy server is set up in the substation; the IEC61850 proxy server is added to a SCD model of the substation as an IED device; simulation proxy is carried out on the IED device in the substation through the IEC61850 proxy server; and the dispatching master station and the IED device in the substation communicate through the IEC61850 proxy server. Information transmission between the substation and the master station is improved, the problems of accuracy and reliability in information transmission are effectively solved, a high-quality and efficient basic information transmission and exchange way is provided for multiple application functions of an intelligent substation through seamless information and model transmission, and a good foundation platform is constructed for power grid dispatching and monitoring.

The invention discloses an intelligent substation interval electrical equipment measurement and control system and method. The system comprises a plurality of cluster measurement and control modules;each cluster measurement and control module comprises a plurality of interval virtual measurement and control units, and the interval virtual measurement and control units measure and control intervalelectrical equipment of an intelligent substation; the interval virtual measurement and control units in any cluster measurement and control module are in one-to-one correspondence with the intervalvirtual measurement and control units in other cluster measurement and control modules; and when the interval virtual measurement and control unit in the running state fails, the interval virtual measurement and control units in other corresponding cluster measurement and control modules are switched from the hot standby state to the running state. By adopting a multi-set cluster measurement and control method, each cluster measurement and control module comprises the same interval virtual measurement and control units, and when any interval virtual measurement and control unit fails, the corresponding interval virtual measurement and control unit is automatically switched to, so that the problems that the number of secondary equipment is large, interval layer measurement and control configuration is single, redundant standby application does not exist are solved, and redundancy configuration of measurement and control functions of interval electrical equipment is realized.

The invention relates to a panoramic model file-based alternating-current sampling cable information visualization method for in-situ protection equipment. Compared with the prior art, the defect thata traditional cable query method cannot meet actual use requirements is overcome. The method comprises the following steps: modeling an alternating-current sampling cable loop of the in-situ protection equipment; obtaining alternating-current sampling cable loop information marked on site; generating two-dimensional code label information; marking the cable position. According to the method, theintelligent substation in-situ protection secondary circuit cable is managed and controlled in an omnibearing mode, visualization of alternating current sampling cable information is achieved throughcable-oriented physical circuit modeling and a cable mark search algorithm, and it is guaranteed that sampling source series nodes are clear and easy to locate and understand.
