It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
In the description of the invention, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " is based on accompanying drawing institutes
The orientation or position relationship shown, it is for only for ease of and describes the present invention and simplify description, rather than indicates or imply meaning
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that the present invention be protected
Protect the limitation of scope.
Below by specific embodiment, the present invention is described in further detail.
Specific embodiment：
In distribution system, bus marco instruction sends equipment can send control instruction by bus, turn on/off solid-state
SSPC passages in power distribution equipment, the working/not working control of load is realized, control instruction can also be sent by switch, Gu
State power distribution equipment gathers the control instruction from switch, according to the SSPC passages inside instruction on/off, realizes load
Working/not working controls.
Distribution system method for diagnosing faults provided by the invention using solid state distribution device is as shown in figure 1, including as follows
Step：
Step 1, solid state distribution device information is obtained, it is defeated that it includes solid state distribution self-check of device measurement information, SSPC passages
Enter voltage status, SSPC passages input control instruction, SSPC passages output order, SSPC passage output voltages state, SSPC to lead to
Road overload protection state and SSPC passage short-circuit protection states；
Wherein, solid state distribution self-check of device measurement information includes the whether normal status information of SSPC passages, and SSPC is solid-state
Power controller, SSPC passage input voltage states pass through the input inside solid state distribution device in the present embodiment preferably
Voltage collection circuit is gathered, and SSPC passage output voltage states are adopted by the output voltage Acquisition Circuit inside solid state distribution device
Collection, SSPC passages input control instruction, SSPC passages output order, SSPC channel overloads guard mode, the short circuit of SSPC passages are protected
Shield state is obtained by the SSPC passages inside solid state distribution device, and solid state distribution device passes through total inside distribution system
Line exports solid state distribution device information；
When carrying out fault diagnosis, bus data analytical equipment is connected on the external bus of distribution system, you can read
Take above-mentioned data.With reference to the power distribution system data read, fault diagnosis is carried out according to following strategy：
Step 2, when load cisco unity malfunction, and solid state distribution self-check of device measurement information shows failure, then judges solid-state
Power distribution equipment failure, detect whether distribution system recovers normal again after replaceable solid state distribution device；
Step 3, when load cisco unity malfunction, and solid state distribution self-check of device measurement information and SSPC passage input voltages
When state is normal, Fault Diagnosis Strategy is：
(1) if bus marco instruction changes, SSPC passages input control instruction is not instructed and become with bus marco
Change, then judge that bus marco instruction sends device fails；
(2) if SSPC passage output orders change, SSPC passage output voltages state does not export with SSPC passages
Instruct and change, then judge that SSPC passages break down, (2) step is by " passage itself determines whether the judgement of failure "
Whether correctly from the point of view of whether itself faulty, when solid state distribution self-check of device measurement information shows normal, then it represents that SSPC passages
Also normally, find that SSPC passage output voltage states do not change with SSPC passages output order when but performing (2) step,
Then illustrate that the malfunction of feedback is wrong, SSPC passages are faulty；
(3) if SSPC passage output voltage states are normal, and change as distribution system distribution control instruction changes, then
Judge that load is broken down；
(4) if the protection of SSPC channel overloads occurs or SSPC passages short-circuit protection occurs, and can not reset, after changing load
Reset successfully, be then determined as that load is broken down, can not still be resetted after changing load, then be determined as solid state distribution device and load
Between line failure；
For the trouble point being determined in step 3, the replacing of corresponding faulty equipment can be carried out, then detects power distribution system again
Whether system recovers normal.
