Description
Technical Field
The application belongs to the technical field of power system communication, and particularly relates to an optical cable routing laying system and a planning method for a transformer substation.
Background
The power system communication is an important component of the power system, is the basis of intelligent scheduling and production management modernization of the power grid, and is the basis for ensuring safe, stable and economic operation of the power grid. The intelligent power grid safely and stably operates various control data and is borne by the special optical cable for electric power, and the reliable operation of the optical cable directly determines the overall safe and stable operation level of the power grid. At present, domestic substation cable channels are classified according to voltage classes whether they are of a general design or a typical design. Specifically, a reinforced concrete or bricked cable trench which is independent and not communicated is designed below the ground level outside the main control room, and the guiding optical cables with the same voltage level enter the special optical fiber distribution cabinet for communication in the main control room of the transformer substation from the same cable trench. Taking a 220kV transformer substation as an example, a plurality of corresponding guiding optical cables are respectively led down from an iron tower at 220kV, 110kV and 35kV voltage sides and enter a cable trench with unique corresponding voltage class, and the guiding optical cables with the same voltage class enter a communication optical fiber distribution cabinet of a main control room through a single channel. Therefore, a potential safety hazard exists in the current on-line transformer substation and the newly-built transformer substation: communications at the same voltage level direct the fiber optic cable to the master control room as a single channel. If a fire accident occurs in the cable duct during operation, the cable duct can directly cause interruption of the guiding optical cable, and the safe and stable operation of the transformer substation and the power grid is affected.
Aiming at the problems, the Chinese patent application No. 201710646776.4 discloses an improved structure and an improved method for the double-ditch design of the transformer substation communication, wherein the improved structure comprises a primary equipment area I, a primary equipment area II, a primary equipment area III, a main cable ditch I, a main cable ditch II and a main cable ditch III. The device comprises a main cable ditch I, a main cable ditch III, a first communicating pipeline and a second communicating pipeline, wherein the first communicating pipeline is arranged between the main cable ditch I and one end of the main cable ditch II, and the second communicating pipeline is arranged between the other end of the main cable ditch II and the main cable ditch III. The improved structure has safety benefit and economic benefit, effectively reduces the safety risk of communication accidents caused by optical cable faults, solves the potential safety hazard of a single channel of the optical cable of the transformer substation, and effectively improves the safety operation level of the transformer substation and even the whole power grid. In addition, the improvement method does not need to change the overall design layout of the transformer substation, has no influence on the civil engineering and facilities of the transformer substation, is economical and efficient, has universality and can be widely popularized in domestic transformer substations.
However, the improved structure of the transformer station communication double-ditch design and the improved method thereof only intercommunicate three cable ditches, are not applicable to the transformer station with more outgoing lines in a single direction and more optical cables, and cannot be convenient for workers to quickly find out the proper cable ditches for laying the optical cables; in addition, the improved structure and the improved method of the transformer station communication double-ditch design do not reasonably plan a transmission network and a protection channel, and are not reliable enough for power grid information transmission protection.

The method for cable routing for a substation according to claim 5, wherein the detour path is: the target transformer substation passes through an intermediate transformer substation connected with the target transformer substation, and then is connected with other transformer substations connected with the SDH equipment through the intermediate transformer substation, and the other transformer substations are connected with the SDH equipment through an optical cable I or an optical cable II.
7. A method of cable routing for a substation as claimed in claim 6, wherein the detour path through which the two 2M protection paths for each substation are located is at least one different cable laying path from the dedicated core path for that substation.
