Telemetry parameter is shown in 2 PCS device communication point table of table
The test case for making main website analog end, issues active and idle target to system under test (SUT) for main website analog end
Instruction, such as total active target value are set as 5MW, and total idle target instruction target word is set as varying DC link voltage to 230KV；Make power grid
BMS system, PCS device business mould in new energy power station is arranged in side BMS system analog end, the test case of PCS device analog end
The parameter initial state value of type, while target component is set and fills in target value, 10 PCS devices and 10 sets for example in energy-accumulating power station
BMS system typing original state, such as every PCS device initially to have work value to be all provided be 0, while the target value of test item is set,
Such as 0.05MW is set as to each device active target value for adjusting test item active for the first time；
Test environment is built, it will be where automatic test lead, main website analog end, PCS device analog end, BMS system analog end
PC machine and system under test (SUT) where PC machine be connected on same interchanger, and configure IEC-104 communications parameter, establish communication and connect
It connects, this is built the production that the period includes test case, test report and an engineer is only needed to spend 3 hours, compared to biography
The period of building of the RTDS analogue system of system is greatly improved, and substantially reduces the period of environmental structure, is greatly reduced
Build cost.
(2) it is clicked in automatic test lead and starts testing button, automatic load test use-case, starting test realizes a key
Formula operation, improves the Experience Degree of user, and main website analog end is sent out according to automatic test lead by com (The Component Object Model) interface
The target value information sent issues active or idle target value to system under test (SUT), and always having work value as defined in test case is 5MW,
It is 5MW that then main website analog end, which issues total active target value to system under test (SUT) by IEC-104 specification message, as test case provides
Target bus voltage is adjusted to 230KV, then it is 230KV that main website analog end, which issues busbar voltage target value to system under test (SUT),；
(3) system under test (SUT) receives instruction and issues remote regulating or remote control command to all devices of PCS device analog end, such as quilt
When examining system receives total active target value and needs to adjust the order for arriving 5MW, according to etc. the strategy of nargin distribution give every PCS device
The active target value of distribution should be 0.05MW, and system under test (SUT) receives reactive command voltage-target when being 230KV, can be according to working as
Target of Reactive Power value is calculated in preceding voltage-target 225KV and random impedance coefficient bound, and calculation method is as follows:
Original busbar voltage target value: U0=225KV；
It is expected that busbar voltage target value: U1=230KV；
Target voltage difference: Δ U=U1-U0=5KV；
System impedance coefficient is R；
The random impedance coefficient upper limit: R1；
Random impedance lower coefficient limit: R0；
Idle difference DELTA Q=Δ U*R；
And system impedance coefficients R is obtained by random impedance coefficient bound:
Random proportionality coefficient rate；
Rate=random number %20000/20000.0
R=R0+ (R1-R0) * rate；
Assuming that the calculated result of R is 10, then idle difference DELTA Q=Δ U*R=50MVar (megavar), and initially idle
Target value is 0, then expected Target of Reactive Power value Q1=0+ Δ Q=50MVar, according to etc. nargin distribution strategy it is inverse to every
The Target of Reactive Power value for becoming device distribution should be Q1/100=0.05MVar；
Due to various uncertain factors such as plant load rate etc. in energy-accumulating power station, actual system impedance value is also certain
It can impacted be in fluctuation tendency, be realized by random proportionality coefficient come the method for computing system impedance value true to energy-accumulating power station
The simulation of environment unstable factor, so as to obtain test data and test result more true to nature；
(4) PCS device analog end is arranged according to the remote control, remote regulating instruction and automatic test lead that receive according to all devices
Original state come adjust every equipment in requisition for according to instruction come the value of the parameter adjusted, such as the work value that has of PCS device, and
Result is fed back into system under test (SUT) by remote signalling, telemetering message, simultaneously also by com interface the state of all devices after adjusting
Information sends automatic test lead, such as active adjusting: 10 PCS analog machines are instructed according to the remote regulating received has work value for oneself
It is adjusted to 0.05MW specified in remote regulating order, and sends the value after every inverter practical adjustments by telemetering message, while
Can real-time update respectively have work value in communication point table, and will actually there is work value to send automatic test lead, in addition, Reactive-power control:
Oneself is adjusted to 0.05MVar specified in remote regulating order without work value according to the remote regulating instruction received by 10 PCS analog machines,
And the value after every inverter practical adjustments is sent by telemetering message, while also can the respective nothing in communication point table of real-time update
Work value, and will automatic test lead actually be sent without work value；
(5) automatic test lead receives the result data of PCS device analog end and BMS system analog end feedback, writes into test
The end value item of report, and error op is done with target value, belonging in error range detects qualified, test result filling
" qualification " is otherwise filled out " unqualified ", and report, which fills in finish, can be reserved for local, is had access to for tester.So as to greatly simplify
The test process of grid side energy storage Monitor Process system, shortens the testing time, improves testing efficiency, has extremely strong reality
Value.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.

Telemetering message sends the value after every inverter practical adjustments, while real-time update respectively has work value in communication point table, and will
Actually there is work value to send automatic test lead；PCS analog machine according to receive remote regulating instruction by oneself be adjusted to without work value it is distant
It is worth specified in transfer order, and sends the value after every inverter practical adjustments by telemetering message, while real-time update is respectively led to
In news point table without work value, and actually will send automatic test lead without work value；
Automatic test lead receives the result data of PCS device analog end and BMS system analog end feedback, writes into the knot of test report
Fruit value item, and error op is done with target value, belonging in error range detects qualified, test result filling " qualification ", no
Then fill out " unqualified ".
7. the automatic checkout system and method for grid side energy storage Monitor Process control system according to claim 6, feature
Be: the test report is saved in local.
